How to choose the right rivet?

Before purchasing a rivet for joining sheet materials, you should understand how to choose the best option. The part consists of two elements - the body and the exhaust rod. When choosing, you need to take into account the following factors:

• Material of manufacture. It is recommended to select a rivet in accordance with the material of the structure. If not observed, this solution may cause corrosion and lead to a decrease in fastening strength.
• Diameter. In this case, the force of the load on the surface is taken into account - the larger the diameter, the higher the load.
• Length. Completely depends on the characteristics of the materials used and their thickness.

Some elements can only be installed if there is full access to the surface on both sides, which should also be taken into account.

Considering the above tips and factors, anyone can easily select the appropriate elements to create a strong connection. You can purchase blind rivets inexpensively in the Toprivet online store.

How to choose rivets?

Blind rivets are a fastening element used in construction for fastening together system parts, facing materials, when installing slopes, drains and installing additional elements. Also used in mechanical engineering and other industries (for example, the production of household appliances). Blind rivets are most often used when installing ventilated facade systems.

Rivet device

Blind rivets consist of a cylindrical drawing rod and body. The rod consists of a head, a break point (between the leg and the head), a leg and a tip, and the body of the rivet consists of an end, a side, a leg and, accordingly, an internal hole for the rod.

Types of rivets

The following types of blind rivets are distinguished:

• Standard.
• Petalaceae.
• Closed.
• Grooved.
• Sealed.
• Split.
• Compacted.
• Reinforced.
• Air and waterproof.

Based on the type of bushing, 3 types can be distinguished: with a flat, wide and countersunk collar.

Blind rivet materials

Depending on the purpose of use, rivets from the following materials are used:

• Aluminum (including anodized and varnished).
• Cink Steel.
• Stainless steel A2 and A4.
• Copper.
• Copper-nickel alloy.
• Polyamide

The rod and body can be made from the same material or from different ones. In some cases, RAL colored rivets are required.

Application depending on body/shaft material

Aluminum/steel rivet . These combined rivets are the most common option. In this case, both high-quality durable alloy AlMg3.5% (with galvanized or stainless steel) and less load-resistant AlMg1% can be used. The latter is called “soft aluminum” - such fasteners are not recommended for use when installing facades and other construction and finishing works where reliability and strength of fastening is required.

Rivet steel/steel . It is used when installing slopes and systems made of galvanized steel, as well as for fastening individual structural elements.

Aluminum/aluminium rivet . AlMg 2.5%/AlMg 3.5% alloys are used. Used for fastening aluminum structures.

Rivet stainless steel/stainless steel . Steel ones are used when fastening structures made of stainless steel.

Installation of blind rivets

During installation, the rivet rod is pulled through the body (sleeve) using a riveter. During installation, the sleeve is deformed by the head of the rod, resulting in strong fixation of the materials being joined. In the separation zone, the rod is deformed. A strong fit of the side to the objects being connected, and the absence of rotation in the parts indicate correct installation.

Separate attention should be paid to the choice of location for mounting the rivets. To the edge of the elements being connected, the minimum distance must be at least 2 diameters of the rivet sleeve, and between the rivets themselves the minimum distance corresponds to 3 diameters of the sleeve. The hole for the rivet is drilled perpendicular to the surface of the parts to be joined. The diameter of the hole for the rivet must be no less than 0.1 and no more than 0.2 mm.

Rivet sizes

The main sizes of rivets include:

• Diameter of the rivet (head).
• Side diameter.
• Rod diameter.
• Side thickness.
• Rivet body length.
• Total length from head.
• Rivet body length.
• Length of the protruding part of the rod.

Features of choosing rivets

When choosing blind rivets, you should focus on:

• Terms of Use. Based on them, they choose movable, sealed, etc.
• Withstand load. Accordingly, the diameter of the fastening elements is selected.
• Materials of fastened sheets. There should be no corrosion at the fastening points.
• The thickness of the materials being fastened. Guided when selecting the appropriate rod length.

Manual riveter (riveter) - how to use and how to choose

A recent fashionable men's trend has become the ability to do something with your own hands. Often, a home craftsman’s kit does not include one of the most useful gadgets today – a riveter.

How to use a riveter correctly

There are several technological methods for attaching various materials to each other:

• gluing method;
• welding;
• threaded connection;
• fastening with self-tapping screws;
• riveting.—With the use of modern riveters, this is a simple operation.—Guarantees a strong and reliable connection of any materials.—Minimum labor intensity.—There are no restrictions on the minimum thickness of the connection.—The fastening can be threaded.—One-sided accessibility is possible.

Note: only electrochemical corrosion between the connecting surfaces or the rivet can become an obstacle.

Difficulties in working with a riveter

There are no technological difficulties when working with a riveter. To make a reliable connection, you need to perform a number of simple steps:

• alignment of bonded surfaces;
  • there should be no gaps. Otherwise, the quality of the fastening will suffer.
• marking and drilling holes;
  • the diameter of the hole should be 0.2-0.3 mm larger than the diameter of the rivet sleeve.
• pressing parts together;
  • If possible, it is good to use clamps or a vice.
• insert the selected rivet into the drilled hole;
  • a bushing with a larger diameter is inserted into the hole. The thinner and longer part of the rod sticks out. The sleeve must be greater than the thickness of the materials being fastened, from 1.0 to 1.5 times its diameter.
  • The skirt should be pressed tightly against the outer part.
• The rod sticking out is inserted into the tool chuck until it stops, strictly along its axis.
• By squeezing the handles, the sleeve is deformed, the inner head of the fastening is formed and the excess part of the rod is removed.
  • When using a tool with a function for collecting rod scraps, there will be no need to remove it from the chuck.

Poor connection quality can occur in the following cases:

• a torn rod leaves a protruding and sharp edge.
  • A larger tool head was used.
• the torn rod remained in the tool chuck.
  • low quality budget model.
  • changing the position of the tool until the rod breaks.
• the rivet has not filled the hole - there is play between the rivet sleeve and the part.
  • The diameter of the rivet does not match the diameter of the hole - a new one must be installed.

Advice: a correctly selected riveter, with a three-point clamp, will significantly improve the quality of fastening.

Manual riveter: which one is better to choose?

The main technical characteristic when comparing different models is the diameter of the rivets.

But the final choice of device depends on how clear the specifics and scope of the work ahead are:

• solving various household problems;
  • It is more logical to choose 2 cheap tool sizes.
  • No additional equipment or cases.
  • If necessary, everything required can be purchased separately.
• major domestic and commercial construction work;
  • Depending on the volume of work, a professional branded riveter is required.
  • The drive can be electric, battery, pneumatic or pneumohydraulic.
• material of the fastening elements used;
  • The larger they are and the stronger they are (steel, stainless steel), the higher the requirements for the power of the tool.
• application functionality;
  • If there is a variety of fastening work in hard-to-reach places, it will require the use of a universal tool.
  • It is necessary to opt for products with a power, lever mechanism and a rotating head.
  • Various drive options are available.
  • A version of the mechanism with a waste collection container will be needed when carrying out work on the roof or fence of a residential area.
• availability of additional equipment.
  • The presence of a case, additional heads and a set of fasteners is always convenient for any work.

Note: the owner’s care when working with the tool is the key to its long and flawless operation.

Types of Hand Riveting Tools

According to the principle of operation, there are three types of the instrument in question:

• exhaust;
  • In this case, a strong, power rod is pulled through a soft, forming sleeve located in a pre-prepared hole. In this case, the sleeve deforms, fills the hole and forms the inner head. After this, when a certain force is reached, the rod breaks off.
  • This is the most popular and popular type of such instrument.
  • Its cost primarily depends on:
    • from the branding of the manufacturer.
    • functionality.
    • Completeness.
  • threaded
    • It is used when it is necessary to have a threaded connection in a thin-sheet rivet assembly.
      • The principle of operation is similar to a drawing tool. But the rod does not break, but is turned out of the formed connection.
    • The price of such a tool is slightly higher than that of a suction tool.
    • Functional:
    • They are equipped with cases with a set of heads and threaded connecting elements.
  • universal.
    • The most expensive and functional devices.
    • They are equipped with cases with a set of fasteners and heads of various sizes.

Advice: if you do not have a head (chuck) of the required size, you can purchase it at a specialized tool store.

Rivet material

When selecting fasteners, be guided by the following characteristics:

• by model;
• by type of head;
• material (sleeve + rod).
  • Al-Mg alloys (the more magnesium, the stronger the alloy).
  • Cink Steel.
  • Stainless steel.
  • Their combinations.
    • Aluminum-magnesium alloy (2.5%) - Aluminum-magnesium alloy (5%). Used in combination with aluminum structures. Insufficient strength. It is better if the bushing is made of aluminum-magnesium alloy (3.5%)
    • Aluminum-magnesium alloy (1%) - galvanized steel (St). The most popular combination of blind rivet materials. The fastener is not sufficiently resistant to corrosion, both on the sleeve and on the galvanized (coating thickness 7 microns) rod. The service life of such a layer is 1 year. Then - galvanic couple AL / St with node destruction.
    • Aluminum-magnesium alloy (3.5%) - galvanized steel (St). The most functional combination, but questions about the durability of the galvanized surface remain.
    • Aluminum-magnesium alloy (3.5%) - stainless steel. Only positive characteristics.
    • Galvanized steel (St) - galvanized steel (St). Good strength properties. Problems remain regarding the durability of the galvanized surface. Additional protection required. Used with galvanized structures.
    • Stainless steel (A2, A4) - stainless steel (A2, A4). The most reliable in terms of strength and corrosion resistance.

Note: the material of the rivets directly affects such characteristics as cost, durability, strength characteristics, and corrosion resistance.

Ease of use

The ease of use of any tool is, first of all:

• minimal physical activity on a person during work;
  • Ergonomic design (FIT Pro HQ 32048).
    • The handles are covered with soft plastic or rubberized.
    • The presence of a protective bracket for fingers.
    • The contour of the handles is formed for comfortable perception of effort during work.
    • The bracket on the handle makes storing the model easy.
  • Low weight indicators, all other things being equal.
  • Reinforced handles or their lever design.
  • Two-handed version of the riveter (SPARTA 405385).
• increasing labor productivity;
  • Use of various types of drives, in addition to manual ones.
    • Electric (AccuBird, RIVIT – Italy, Gesipa – Germany)
    • Pneumatic (RL10, MESSER AHR-300)
    • Pneumohydraulic (Taurus2, Taurus4, Gesipa FireFox 2C)
  • its functionality.
    • The presence of a rotating head (MATRIX 40533, Kraftul -3 31173-H6).
    • Universal (pull/threaded) design option (ZUBR EXPERT 31196, KRAFTOOL INDUSTRIE 31182)
    • A sufficient number of replaceable heads (cartridges) with a set of fasteners.

Note: with an increase in the number of options and professional orientation of the tool, its cost increases significantly. Starting from budget hundreds of rubles and ending with many tens of thousands.

Adaptations

Indispensable attributes for high-quality riveting work are well-known tools and devices:

• drill;
• core with hammer;
• a set of drills from 3 to 5 mm in diameter, in increments of 0.2 mm;
• calipers;
• a set of replacement heads for the riveter;
• clamps or vice of the required size;
• rivets of the selected type and size;
• container for collecting rod scraps;

Rivets. How to calculate the required rivet length

A rivet is one of the simplest types of fasteners for creating permanent connections. In the general case, this is a rod or tubular part that has a supporting “embedded” head of a certain shape at one end. It is installed in the connection, as the name suggests, by the riveting method (as well as shrinkage, rolling, broaching, explosion).

Based on their shape, rivets can be divided into several main types:

• Rivets with a closing head (there are solid, hollow and semi-hollow)
• Rivets with broaches (also called tear-off or pull-out rivets)
• Threaded rivets (also called riveting nuts)

Rivets with locking head

Historically, rivets with a closing head were the first to be invented, which is why they became the most widespread. These rivets have a head on one side. The second head, called the closing head, is formed using a rolling or riveting tool: riveting hammer, pliers.

According to the shape of the head, rivets with a closing head are divided into:

• Round head rivets
• Countersunk rivets
• Rivets with semi-countersunk head
• Flat head rivets (with barrel)

They also differ structurally by the presence of a hole inside the rivet:

• Solid rivets - no hole
• Hollow rivets - tubular - have a through hole
• Semi-hollow rivets - for flaring - have a blind hole

Materials for rivets

Rivets with a closing head can be made from a variety of metals and alloys that lend themselves well to plastic deformation.

The most widely used materials are:

• Steels - mainly ductile high-boiling steels 03kp, 05kp, 08kp, 10kp, 15kp, 20kp
• Stainless steels - austenitic steels 12Х18Н9, 08Х18Н10, 03Х18Н11, 12Х18Н10Т
• Aluminum alloys - the most applicable alloys are AD , AD1 , aluminum-magnesium alloys AMg2, AMg5, AMg5P, AMg6, alloys AMts, V94, V65, D1, D16, D16T, D18, D18P, D19P are also used
• Brass alloys - mainly L63
• Copper - grades MT, M3

Marking of rivets by materials

Rivets can be marked on the head for subsequent identification. The marking can be convex or concave (branding).

The following is a table with the accepted marking of basic materials in the form of dots or dashes.

Aluminum alloys	Steel	Copper and brass
B65	D18P	D19P	AMg5	AMts	AD1	20GA	10, 20, 12Х18Н10Т	M3, L63
no label	no label	no label

Determining the length of the rivet

Correct installation of the rivet involves creating the full shape of the closing head and the absence of any excess gaps or sagging. To install the rivet correctly, it is necessary to determine the length of the rivet body, which depends on the thickness of the materials being riveted and the type of rivet.

“Handbook of mechanical engineering designer”, edited by Anuriev V.I. suggests using one universal formula for all rivet head shapes. Common sense suggests that this approach is erroneous - so we will use formulas from another source: “Fundamentals of Design”, edited by P.I. Orlov, 1988.

Rivet design	Allowance “H” for rivets without gap	Allowance “H” for rivets with a gap
H=1.2d	H≈1.2d+0.1S
H=0.54d	H≈0.5d+0.1S
H=0.6d	H≈0.5d+0.1S
H=0.8d	H≈0.7d+0.1S
H=d	H≈0.9d+0.1S
H=1.2d	H≈1.1d+0.1S

Having calculated the required allowance size using the formula, you can determine the length of the rivet L by the allowance value H to the thickness of the materials being riveted S. Then you need to select the closest rivet length from the standard range of lengths. A standard range of lengths has been approved for rivets, according to which they are produced (in mm):

• 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 45, 48, 50, 52, 55, 58, 60, 65, 70, 75, 80, 85, 90, 95, 100, 110, 120, 130, 140, 150, 160, 170, 180

Example of calculating the length of a rivet

For example, we need to rivet several sheets with a total thickness of 32 mm; We will rivet without gaps with rivets with a semicircular head Ø6 mm (1st design in the table).

d = 6 mm

S = 32 mm

H = 1.2d = 1.2 x 6 = 7.2 mm

Therefore, it is necessary to use a rivet with a shank length

L = S + H = 32 + 7.2 = 39.2 mm

We choose the closest length from the standard range - this is 40 mm.

As a result, we found out that to rivet a package of sheets with a thickness of 32 mm, we need a rivet of size Ø6x40 mm.

How to correctly calculate the length of a hammer rivet

A rivet is one of the most convenient and quickest fasteners to install, providing a reliable permanent connection. Today there is a huge variety of shapes and sizes of riveting fasteners, but hammer rivets were the first to be invented.

They were used in the construction of ships, bridges and other metal engineering structures, where they successfully replaced welded joints.

Today, this oldest type of fastener is made from modern materials, so it has not lost its popularity and has even expanded its scope of application.

Operating principle of a hammer rivet

A classic hammer rivet is a rod with a rivet head of a certain shape (semicircular, countersunk, semi-countersunk, flat).

The closing head is formed from the opposite end of the rod by plastically deforming it using a riveting hammer and a special impact mandrel, which gives the head a neat semicircular shape.

In this case, massive support must be provided from the side of the mounting head. Obviously, to install such a rivet it is necessary to have access from both sides of the surfaces being fastened.

Determining the length of a rivet with a closing head

To correctly install the rivet fastener, it is important to accurately select its length so that it is possible to create a closing head of the required shape from the protruding part of the rod and obtain a connection without gaps. The length of hammer rivets produced varies from 2 to 180 mm and is selected based on the thickness of the package of materials being fastened.

First you need to determine the length of the protruding part of the rod (allowance). For the version with a semicircular head, the allowance is 1.21.5d, and for the version with a countersunk head - 0.81.2d, where d is the diameter of the rod. Based on the obtained allowance value, it is easy to calculate the total length of the rod by adding to it the thickness of the materials being riveted - S.

• Length calculation for round head rivet: L = S + (1.21.5d)
• Countersunk head rivet length calculation: L = S + (0.81.2d)

Calculation example:

It is required to rivet materials with a total thickness of 41 mm using a countersunk rivet Ø8 mm

L = 41 + 0.8 x 8 = 41 + 6.4 = 47.4 mm

Then we select from the existing standard range of rivet lengths the value closest to 47.4, that is, 48 ​​mm. So, to create a hidden rivet connection of sheets with a thickness of 41 mm, we need fasteners of size Ø8x48 mm.

Hammer rivets come in a wide variety of diameters ranging from 1.0 – 36 mm. The diameter of the hole drilled in the materials must ensure free insertion of the rod, while the size of the gap between the body of the rivet and the walls of the hole must not exceed the parameters prescribed in GOST.

So, to obtain high-quality riveting, the gap for parts with a diameter of up to 5 mm is no more than 0.1 mm, and for parts from 5 mm in diameter is no more than 0.2 mm. When materials are riveted with a countersunk rivet, a chamfer is removed under the head in the hole at an angle of 60° - 90° to a depth corresponding to the height of the embedded head.

Threaded rivets: types, sizes, devices, how to install

A rivet is one of the most convenient and quickest fasteners to install, providing a reliable permanent connection. Today there is a huge variety of shapes and sizes of riveting fasteners, but hammer rivets were the first to be invented.

They were used in the construction of ships, bridges and other metal engineering structures, where they successfully replaced welded joints.

Today, this oldest type of fastener is made from modern materials, so it has not lost its popularity and has even expanded its scope of application.

What is riveting

The mechanical connection of parts using a series of rivets is called riveting, and the connection itself is called a riveted seam. It is used where it is inconvenient to weld parts or where non-weldable materials are joined.

Not only metals are riveted, but also parts in clothing, accessories, etc. are connected in this way. But there it is more of a finishing touch than a loaded connection. So next we will talk about riveting in construction or home improvement.

In principle, you can use a screw connection instead of riveting, but bolts and nuts are more expensive, and their installation takes longer.

This is what a rivet joint looks like

If we talk about installing fences made of corrugated sheets, rivets are more reliable, since they can only be removed by drilling out the fasteners. When installing screws or self-tapping screws, they can be unscrewed and both metal and hardware can be removed. In some cases, riveting is more convenient when installing a roof made of corrugated sheets or metal tiles. On the roof, installing screw connections is problematic and time consuming. But rivets, and with a good tool, can be done in an hour or even less.

Most common use in private households

How are parts connected using rivets? The rivet is installed in the prepared through hole. It has a head that rests on the material and the rod. During the riveting process, the end of the rod is flattened, changing shape under the influence of force. Therefore, ductile metals are used for these hardware.

Device of blind rivets

Structurally, the blind rivet is made in the form of a cylindrical rod with a semicircular or flat side. Also, the fastening element can be made in a hidden design, in which the head is hidden in a special recess in the base material. A single structure of fastening elements is obtained only by using a special tool, which allows obtaining a sufficiently large force to fasten the structural parts.

Types of rivet seams

If we talk about the method of joining sheets, then riveted seams can be overlapped (one sheet overlaps another) and end-to-end. Joint seams can have one or two overlays. With overlays they are more reliable and are used in critical and loaded places.

Types of rivet seams: overlapped and butted with overlays

According to the location of the rivets:

They can be located opposite each other or in a checkerboard pattern. Seams can be strong, tight (sealed) or durable-tight. Dense ones are made using elastic gaskets placed between the parts to be connected. Durable and dense ones are used mainly in boilers. Now they are more often replaced by welding.

Alternative Fasteners

The products perform their main task - to fasten metal (and not only) parts - and always guarantee the reliability of the resulting structure.

They are durable, easy to install and resistant to chemicals. At the same time, they are compact and versatile. Today they are trusted by craftsmen in various fields: shipbuilding, aircraft construction and auto repair.

Rivets for plastic and metal are widely used in electrical engineering, in the manufacture of containers, and in the construction of bridges. Often used as an alternative to welding, for example, in explosive and fire hazardous facilities. Only they can cope with fastening parts in places where access for other types of connections is limited.

Types of rivets

What is a rivet? It is a cylindrical rod of ductile metal (may or may not be hollow) with a shaped head at one end. This head is called a mortgage. During the installation process, due to the flattening of the metal of the rod on the second side, a second head is formed. It is called closing (closing).

There may be composite rivets (such as the popular blind or screw rivets), which consist of a body and a shank. But this does not change the essence: the embedded head rests on the material, and at the other end, due to the plasticity of the metal, a second head is formed. It is simply formed due to the fact that the rod is extended and the expanded part crushes the second part.

How to choose a manual riveter

It has never been easier to make a rivet than it is now. This process is carried out using a riveter. This is a simple mechanical tool that resembles the action of pliers. The rivet is created by pressing the handles, after which the lever system is activated, inserting the rivet into the hole. We’ll look at how to choose a manual riveter so as not to waste money in vain, in this article.

What types of riveters exist

If recently riveters were bulky and used in workshops and workshops, now designers have improved the model by creating compact, lightweight, easy-to-use riveters. They are used for household needs. The rivet is inserted without any effort. The main thing is to make the holes in advance.

Threaded and pull-out riveters have been created. The operation of the extractor is based on pressing a special ball, which flattens the rivet and enters the tube after pressing the handles.

The principle of operation of a threaded ball is to retract the ball due to a rotating thread.

Both types of riveters are simple and easy to use, but pull-out ones are cheaper, which makes them more attractive to buyers.

Riveters differ depending on the drive:

• pneumatic;
• mechanical;
• pneumohydraulic.

The two above types are heavy and are used mainly in production, while mechanical ones are small hand tools for household use.

The designers improved the manual riveter and created a model for working in hard-to-reach places with an adjustable head. This is the most acceptable type for craftsmen, as it allows you to perform complex work.

There are universal riveters designed to perform both simple and complex work. They are equipped with additional heads of different sizes and fasteners.

Riveters can be one-handed or two-handed. The two-handed model is an undeniable tool for working with particularly strong rivets. The one-handed riveter makes it easy to rivet in hard-to-reach places.

How to choose a riveter

For the average user who needs a tool occasionally, the main requirement when purchasing will be a low price. But professionals, craftsmen working at home, will need a good model that meets the functional purpose. Let's look at the points you should pay attention to when purchasing:

• The riveter must be made of durable steel elements, the handles are equipped with high-quality plastic;
• choose a model from well-known manufacturers;
• if you have to perform complex work, then it is better to purchase a tool with a rotating head;
• the pistol-shaped model has more reliable performance characteristics;
• for constant operation, it is better to purchase an electric model; in this case, the battery will be ineffective;
• if you are dealing with strong materials, then you will need a more expensive and reliable riveter.

Advantages of the riveter

The riveter is practical, its main advantages:

• nice design;
• convenient design;
• minimal physical effort by the master;
• contribute to increased labor productivity.

To work with a riveter you should:

• select the correct size of rivets - if the rivet turns out the first time, then it means it matches; if it fails, you should change the size of the rivet. Depending on the thickness of the material, the size of the rivet is selected. Sheets 5mm thick require a rivet 8mm long and 2.4mm in diameter. Accordingly, the hole is drilled 2.5 mm. For a 12.5 mm sheet you will need a 16 mm rivet with a diameter of 4 mm;
• Before pressing the lever, make sure that the head fits snugly against the head;
• for successful work, it is recommended to select rivets and sheets from homogeneous materials;
• To constantly work with rivets of different diameters, you need to have at least two riveters, for example: one-handed and two-handed.

Recommended riveters

Of all types of riveters, the NOVUS J 60 products have proven themselves well. A reliable model that works flawlessly. The disadvantages include the somewhat heavy weight, as your hands get tired when working.

How to choose a manual riveter: selection and use of tools

One of the most common methods of obtaining a permanent connection is riveting. It is used in everyday life, construction work, and production. The advantages of the operation are reliability, strength of bonding of materials and low time consumption.

The fastening element is a rivet, and the working tool is a riveter.

Design features

According to the design, there are 2 main types of tools. The differences between them are clearly demonstrated by photos of riveters:

Classic with two handles. Externally they resemble pliers. Riveting occurs by squeezing the handles and activating the ratchet mechanism.

Rocker (accordion type) with one handle. They are considered professional tools and are used where it is necessary to install a large number of fasteners.

Which of the two types should I choose, amateur or professional? The answer depends on the expected frequency of use.

For minor home repairs, there is no need to buy expensive professional equipment. In cases where significant force is required when riveting, it is better to use modern and powerful riveters.

Power type

The classification of riveters is not limited to the division into household and professional. The second important parameter that distinguishes different models is the type of power supply.

Manual

Manual riveters are the simplest devices with rubberized handles. Productivity depends on the force required to close the handles. Some tools are equipped with a rotating head, allowing riveting in hard-to-reach places.

Rechargeable

Compared to manual versions, they contain a built-in battery, the energy of which is directed to striking and forming a rivet. Outwardly it resembles a pistol; on the body there is a “trigger” - a button for activating the device.

Depending on the battery capacity, it is designed for installation of 500-1000 rivets. It is not recommended to use in places with high humidity and dust.

Pneumatic

These are the most productive devices powered by a compressor. Structurally more complex than manual and battery-powered analogues. The device has a compartment for compressed air, a fitting for connecting a hose and a pusher.

Types of rivets

In construction stores you can find only two types of rivets - blind and threaded. Based on this, there are 2 types of instruments:

Exhaust riveter. It operates on the principle of pulling an internal power rod through a soft outer casing. In this case, the latter is deformed, filling the entire space of the hole. At a certain moment, when the force is maximum, the leg of the rivet breaks off, and a head forms on the surface of the part.

Threaded. The essence of working with it is to deform the end of the threaded rivet so that it is flattened and pressed into the hole.

It costs more than a blind riveter, but has a number of advantages: it becomes possible to install bolts, the connection is reliable and resistant to mechanical stress.

Rivets

Among the main dimensions of a rivet are length and diameter. It is worth considering that the thicker the parts being fastened, the longer the fasteners are needed.

For example, rivets 2.4x6 mm are designed for fixing materials up to 4 mm thick. If the length of the rivets is less than required, the head will not be able to form; if it is longer, it will form far from the parts.

In both cases it will not be possible to obtain a high-quality assembly. It is important that the chosen fastener fits the riveter attachments.

How to use

Despite the popularity of this device, not everyone knows how to use a riveter. Step-by-step instructions for beginners who are using the tool for the first time:

• A through hole with a diameter equal to the diameter of the rivet is drilled in the parts.
• A rivet is inserted into the resulting cavity so that its short part is inside.
• A riveter attachment is installed on the fastener core, and the handles are compressed.
• After several squeezes of the handles, the rod breaks off, forming a strong connection.

Secrets of choice

If working with a riveter is not so difficult, then the question of how to choose a riveter can confuse many. Experts advise paying attention to the following nuances:

Case material. Plastic tools are short-lived and not designed for daily use. Therefore, for such conditions it is better to choose products made from steel.

Functionality and equipment. Preference should be given to those devices that allow you to work with fasteners of various sizes. To do this, the kit must include replaceable nozzles and a waste storage container.

Weight. Professional riveters cannot have a small mass comparable to household models.

Finally, the manufacturer plays a big role in purchasing a high-quality and durable riveter. Before purchasing, you should read reviews about the product. This is the only way to avoid wasting money.

Manual riveter - which one to choose and how to use

A recent fashionable men's trend has become the ability to do something with your own hands. Often, a home craftsman’s kit does not include one of the most useful gadgets today – a riveter.

How to choose rivets and riveter?

In the construction of any objects, there comes a time when you need to firmly connect some parts.
Bolts are expensive and significantly increase the weight of the structure, screws are a lot of hassle, and nails will not provide the proper load on the fastening. In such situations, it is best to use rivets.

How to choose rivets for simple tasks? When purchasing, you need to take into account their length, the material from which they are made and the actual type of rivets. First of all, they are divided into threaded, with a broach, and with a closing head.

The former are used in the construction of electrical equipment, mechanical engineering and where permanent fastening is not always a suitable option. They are installed using a special riveter, but in everyday life they often use a regular screwdriver. The most common type of rivets is blind rivets.

They are used for fastening thinner sheet metal.

What are the advantages of rivets?

Their main advantage is that for fastening you only need access to one side of the material being riveted. Since after installing the rivet there is a hole in it, you can use this to pull wires through it. Rivets are also distinguished by the type of heads.

There are: hidden, semi-secret, semicircular and flat. The countersunk head fits the level of the material and, as a result, the connection becomes more aesthetically pleasing. Blind rivets have heads that are larger in diameter, which distribute the load more evenly.

This is important when riveting delicate parts.

The photo shows the process of installing rivets

The rivet material should be selected based on what exactly will be riveted and under what conditions the operation will occur. They are made from different grades of steel, aluminum, copper, brass, and plastic.

For example, aluminum rivets are widely used for fastening corrugated sheets for fences or external cladding of buildings.

Each type has its own advantages: steel rivets can withstand heavy loads, copper ones are quite ductile, and plastic ones are not subject to corrosion.

How much load can rivets withstand?

It is also worth considering the future load on the rivets. The higher the diameter of the rivet, the stronger it is. Aluminum or copper rivets are quite suitable for roofing, building cladding or fences. They are cheaper, lighter, and easier to work with.

Each type of rivet has its own type of tool. For high-quality and reliable installation, it is important to choose the right riveter. They are manual, battery and pneumohydraulic. In turn, everyone is divided into professional and amateur.

The former are made of the most reliable alloys, can operate in almost any weather and perform large volumes of work.

Of course, for household purposes you shouldn’t spend money on an incredibly expensive tool that won’t be used at all after the work is completed.

Types of rivets

• Hammer rivets (classic).
• Tubular, semi-tubular and piston rivets.
• Mortgage rivets.
• Threaded rivets.
• Blind rivets.

Choosing a riveter

Welding is an excellent way to join metals, but it is not always convenient or possible. An alternative is riveting. But to install rivets you need to select a riveter. Read on to find out how to do this.  

What is a riveter and how does it work?

Riveters or riveters are devices for installing rivets. There are special tools for different types of fasteners. There are separate ones for blind rivets. There are also universal models, but they belong to the group of professional tools, and accordingly, they cost a lot.

One use case

To choose the right riveter, it is advisable to understand how it works. Regardless of the type of rivets with which the unit works, the principle of riveting is always the same: the device flares the second (distant) part of the rivet, forming the closing head. Only the flaring method may differ:

• When installing blind rivets, the jaws grasp and pull the rod. At the end of the rod there is a ball that rests against the edge of the rivet body and crushes it. When a certain force is reached, the rod breaks off. The work of a riveter when installing blind rivets
• The installation of screw rivets is different. There is a thread inside the hollow body. A screw of suitable diameter is screwed into this hardware. When twisted, it begins to tighten the edge of the rivet, due to which the ductile metal is flared (see video below).
• When installing hollow rivets (piston rivets), simply flaring occurs with a cone-shaped nozzle. Piston rivets are used in unloaded places, but more often not in construction, but for finishing or when joining parts made of leather, fabric, etc. Piston rivets are the easiest to install, but they also have the lowest reliability. They are rarely used in construction, except in crafts.

In general, the process is clear. As you can see, the only differences are that in one case you need to pull the rod, in another you need to turn the screw, in the third you press the conical nozzle. When choosing the type of rivets, please note that the tool for rivets is inexpensive, but for screw rivets it usually costs a lot. This basically limits the use of screw rivets. Well, and because they are hollow, they are not airtight.

Selecting the drive type

Before choosing a riveter, you need to understand what they are. Let's start with the drive.

• Manual (power). To install the rivet, you need to squeeze the handles. Sometimes significant efforts have to be made - for hardware with a diameter of 5 mm or more. The most reliable and inexpensive. This is a justified choice if the tool is purchased for a one-time use - installing roofing material, putting up a fence, sewing up slopes. When using hand tools, you will have to make physical efforts
• Electrical. There is almost no effort - hold the tool and pull the trigger. More expensive, but also more productive models.
  • From the network. Not too expensive, so you can buy them for home use. But not every construction site has a source of electricity, and cords/extension cords are a real hassle.
  • Rechargeable. With the same performance, they are more mobile, but they weigh more (the battery itself also has weight), and they are more expensive. Riveters can be manual, battery-powered, electric, hydraulic
• Pneumatic and pneumohydraulic. The most reliable and productive tool. But it is worth buying only for professional use. After all, you also need a compressor.

review of the MILWAUKEE 2550-20 M12 RIVET TOOL cordless riveter.

For household use, manual riveters are purchased. But even this “simple” tool is not easy to choose. First of all, the range of prices is surprising - from $5 to several hundred dollars. How to navigate here? Let’s say right away that it’s definitely not worth taking something too expensive for a one-time use, just like one that’s too cheap. The rest needs to be figured out.

Types of manual (mechanical) riveters

There are three types of manual rivet setters:

• one-handed;
• two-handed;
• harmonic.

One-handed ones are designed for small fasteners - up to 5 mm. They differ in that their working handles are at an angle of 90° to the installation axis. That is, the handles are pointing down. It is convenient because you can work with one hand. The disadvantage is the small “range” of sizes that the device can work with.

Two-handed ones are large in size; they can also install rivets of large diameters - up to 8 mm. You can distinguish them by their appearance - long handles that are in the same plane as the working jaws. It makes sense to choose a two-handed riveter if you plan to use large diameter rivets.

Types of manual riveters: one-handed, two-handed, accordion

Mechanical accordion riveters are often used with large-sized fasteners. The presence of that very “accordion” allows you to install large-sized fasteners with less effort. Such a device usually has a more expensive tool and is more often used by professionals.

Choosing the type of manual riveter is not too difficult. If you need a reliable machine, choose from two-handed models. Their design is simpler, there is almost nothing to break. At normal quality they are indestructible. If you will only install small fasteners - no more than 2-3 mm, then it is more advisable to use a one-handed one. It's more convenient for them to work.

Selection criteria for manual rivet installers

So, if you need to choose a manual riveter, pay attention to the following parameters:

• The type of fasteners with which the unit works (screw, pull-out, piston (eyelets), universal - which installs all types of rivets).
• Maximum and minimum rivet sizes.
• Number of nozzles for rivets.
• The fastener material with which the tool works (steel, aluminum or only copper and brass).
• What is the instrument itself made of? Better - stainless steel or aluminum alloys. Screw-type manual riveter: pay attention to the dimensions of the fasteners that can be installed

Another thing to pay attention to is the handles. The rubber pads on them should be made of good rubber. The handles themselves should be comfortable for you, so you can work faster and longer. Also pay attention to the possibility of fixing the handles when not in use - there is a special wire loop that holds the handles together. This is convenient and important when storing.

Selecting a blind riveter

Most often you have to work with blind (traction) rivets. They are convenient and inexpensive. The tools to install them don't cost too much either. In addition to the parameters listed above, in order to select a rivet tool for traction rivets, you also need to pay attention to some special characteristics and options.

• The number of clamping jaws (petals) in the collet . The tool grips the rod and pulls it to form the closing head. So, there can be two or three petals. Double-lobed ones are cheaper, but when grabbed, the rod can become skewed and get stuck. You have to take it apart and put it back together again. It’s inconvenient, and time is running out. There can be several forms
• Presence of a ratchet . When working with strong rivets (steel), it is important to correctly calculate the force. A ratchet helps with this.
• Container for collecting broken rods . During operation, the excess rod breaks off. If there is no container, they often end up underfoot and then have to be collected. The presence of capacity solves the problem, but has almost no effect on the price.

Now you know how to choose a riveter for blind rivets. Having selected several models that suit you in terms of characteristics, inspect them and hold them in your hands. If possible, try it a couple of times at work. This will make it easier to understand which tool is more convenient for you to work with and it will be easier to make a choice.

Drill/screwdriver attachment and selection features

When doing a large amount of work using manual riveters, your hands get very tired. Of course, there are rechargeable ones, but the price for them is not at all pleasing. And if you only use it occasionally, it is not advisable to buy a power tool. In this case, you can compromise - purchase an attachment for a drill or a screwdriver for installing rivets.

This is a small adapter (nozzle) that is inserted into the cartridge. They are available for screw and blind rivets. If desired, you can find it for other types of fasteners.

Adapter (nozzle) for drill for installing blind rivets

The principle of operation of a drill with a nozzle for blind rivets is no different - the tool still pulls on the pin, then breaks it off. You just have to get the broken “tails” out yourself, switching the drill to reverse. In the case of using screw rivets, reverse is also required - to remove the nozzle from the installed fastener.

Drill attachment for installing screw rivets

The choice of rivet attachments for a drill is similar: in type, size and material of the attachments. Well, the shank must fit the power tool chuck. Also pay attention to the presence of a handle. This is a non-critical parameter, but it improves ease of use.

A drill with a screwed attachment is heavy and unstable. Therefore, when working, be sure to hold the nozzle with your hand, fixing its position. To avoid holding on to the nozzle, put on a handle.

In this version, the unit is more convenient to use, and you can more accurately control the position.

How to choose a riveter: manufacturers and prices

When choosing a specific model, many rely on prices. But the spread is very wide - there are very cheap ones and almost identical in appearance, but many times more expensive. Even ten times more expensive. It’s worth saying right away that even for one-time work, buying a very cheap riveter is too risky. It may not work at all or work through the stump-deck.

If you only want to rivet a fence, for example, even then you will have to install hundreds of rivets. If you have to disassemble the tool after every 2-3 rivets, you definitely won’t like it. To choose a riveter that works well, look at the average price range.

• Stanley MR 99. Stanley is the oldest American company.
• NOBUS. Inexpensive tool, works reliably.
• Gesipa. A well-known company, but not everyone praises it. There are definitely cheaper ones that work at least as well.
• YATO copes with steel rivets better than Chinese ones with aluminum ones. So that you can estimate the price range
• NWS is a German company. The quality of the instrument is excellent.
• Topex. In some models I liked the ability to move the “spout” 90 degrees. Convenient if you have to work in hard-to-reach places.
• KRAFTOOL. All the tools are good and so are the riveters.

If you plan to use a riveter in professional activities, you need to choose a more expensive one. The company - at your own discretion, but from the category of professional or semi-professional models. Perhaps they do not differ structurally, but they have a longer resource and service life. That is, they are made more reliably and efficiently. And this explains the difference in price - more expensive/high-quality materials were used.

How to choose rivets

Many people, upon opening this article, may think about how difficult it is to choose a rivet. However, if you scroll through it further, you will understand that this stage of work has much more nuances than it might seem at first glance.

Rivets are one of the oldest fastening tools in the world. Essentially, a rivet is a smooth cylindrical rod, the material being primarily metal. The design is simple, head on one side, base on the opposite end.

What sets rivets apart from most fasteners is that they are permanent. After installation, they cannot be removed; they have to be broken during dismantling.

Installation, on the contrary, is quite simple: holes are prepared in the material, drilled or punched in advance, a rivet is inserted, after which the protruding end is usually driven in, thereby tightly fastening the two parts.

The initially existing head is called a factory head, while the one obtained by deformation is called a boxwood or workshop head.

There are many styles of rivets, so the range of applications, characteristics and possible materials is also extremely diverse.

So, a rivet is a fastening element used to join sheet material. Accordingly, if you are thinking about how to choose a rivet, answer yourself two main questions: “for what material?” and “where will the attachment point be?”

Now let's talk about where rivets can be used. The areas of their use are so vast that there is neither the time nor the energy to read the article to the end to list everything, so we will only talk about the main ones:

• Construction sector. It can often be found when fastening and installing ventilation systems, facade elements, fastening sheet materials, frames, cladding and other construction work.
• Mechanical engineering. At fastening points for almost all equipment, including cars, heavy equipment, airplanes, trains and others.
• Household goods. All modern household appliances use rivets, including electrical equipment.
• Food and medical industry. Many food equipment, tanks, tanks are also made using rivets.

Accordingly, in order to select rivets, you need to know the material for which they will be used, the fastening technology and the expected operating conditions.

How to choose rivet material?

One of the main selection criteria is the material from which the fastener will be made.

Rivets can be:

1. Aluminum, resistant to corrosion, tolerates chemically aggressive environments well, can be used as decorative elements (lacquered aluminum), used for fastening materials of external structures or in units exposed to aggressive environments;
2. Stainless steel, not susceptible to corrosion and aggressive environments, used for the food industry, external structures and chemical plants;
3. Galvanized, not subject to corrosion, can be used for many types of designs on the streets, as well as for units in difficult operating conditions;
4. Made from polyamide or plastic, this fastening option is suitable for bendable sheet material;
5. Copper, ideal for installing copper roofing, as well as elements of façade structures, are resistant to corrosion, are non-toxic, and are very durable;
6. Colored, ready for painting, everything is simple here, the products are ideal for painting, and the paint will not peel off for a long time.

How to choose a rivet shape?

First, decide on the size and length of the rivet. The length is selected depending on the thickness of the sheets being fastened and the diameter of the rivet. The larger the diameter, the greater the load the fastening unit will bear.

• A blind rivet is used to fasten building materials to the main structure.
• The rivet nut has a threaded thread that allows you to connect not only sheet materials, but also additional structural elements.
• With a wide side, they are designed for fastenings with increased loads, ensuring the reliability of structures.
• The countersunk head of the rivet will make the fastening invisible, which is important for “finishing” work.

If you have already been able to choose rivets, then before purchasing you should definitely inquire about the compliance of the products with international standards and GOST.

Solid Head Rivets
An original rivet design dating back to the Bronze Age. Hard rivets can be deformed simply with a hammer, crimper, or rivet gun, depending on the size and softness of the material. One of the most reliable, simple and safe types.

High Strength Steel Rivets
Structural steel rivets have been used for hundreds of years and have been the primary rivets for fastening metal structures. Although amazingly strong, they require several skilled workers to install and must be heated immediately before use to make them soft enough to warp.

Tubular Rivets
Semi-tubular or tubular rivets have a dimple or hole at the end opposite the head, making it easier to deform and requiring less force. Most popular for general consumption.

Blind Rivets
Blind rivets are tubular rivets, more commonly known as pop rivets. Their peculiarity is that only one working side is required for installation. There are also many options for solutions and designs. Blind rivets are ideal for areas where access is only possible from one side.

Threaded Rivets
Threaded rivets are another form of blind rivet with a short mandrel. The design is a sleeve with an internal thread; after fixing, the riveter rod is screwed into the center and the front wall is fixed, while the sleeve is crushed, creating a fixed connection. Can be used when the hole does not go through the entire sheet, panel or block.

Self-closing rivets
These rivets do not require a hole for installation at all. Instead, a self-closing rivet has an end that is designed to perforate through the top sheet materials into the bottom sheet materials. This requires a special tool, a riveter, for industrial purposes, usually uses a pneumatic one, it creates a pocket in the block into which the end of the rivet expands, holding the connection.

Rivets for a wide range of applications Today, threaded and blind rivets are mainly used in large quantities, in both cases a tool is required.

But if we talk about threaded solutions, the advantages include reliability and strength, while the disadvantages include low riveting speed and high cost; Blind rivets are used when speed is needed, and there are thousands of fixation points.

The material used for rivets is mainly steel or aluminum, less commonly brass and other metals. Depending on the industry and requirements, materials are also selected. Here it is necessary to take into account both the strength of the rivets themselves and the elements being fastened, and, of course, the corrosion properties.

More about the classical design
This method is widely used to this day; its reliability and simplicity, despite the somewhat archaic and labor-intensive nature of the process, are undeniable advantages; the method occupies a leading position in the aircraft industry, in the design of bridges and other industrial-scale objects.

Standards for riveted joints
Each rivet has its own GOST standards, compliance with which during manufacturing and directly during riveting gives the maximum result. For example, in the construction industry, when working with highly loaded steel structures, they use Soviet GOST standards; compliance with them gives the best strength.

Summarize

In conclusion, it is worth noting the pros and cons of the rivet connection in general; they are relevant for all types of rivets and fully apply to modern types: pull and threaded.

Pros of using rivets

• High installation speed
• Strong connection fixation
• Pressure density
• Possibility of fastening thin-sheet workpieces
• Security of fastening connection
• Low price

Disadvantages of connections with rivets
To be fair, it is worth noting three main disadvantages, depending on the area of ​​application, they can be classified as implicit.

• The rivet type of connection is intended strictly for fastening fixed parts.
• The connection is permanent.

  To disassemble, you will have to cut or drill out the head of the rivet. Which complicates dismantling.

• Special equipment required. To work with modern threaded and blind rivets, a riveter is required.

  A high-quality tool costs money, but it significantly speeds up installation and increases reliability.
