Rivets and Types

What are rivet and riveted joint?

The riveted joint is a permanent joint cause rivet is a permanent mechanical fastener. A rivet is a cylindrical shaft with a head on one end and the opposite end known as a tail.

Rivets are generally made of mild steel, but at times they are also made of brass, copper, and aluminum, etc. Used in structures, bridges, sheet metal operations, ships, and many industries.

Parts of a Rivet

Following are the parts of a Rivet:

  1. Head
  2. Shank and Body
  3. Tail

#1 Head

The uppermost part of the rivet is called the “head.” These are made of different types according to different jobs.

#2 Shank and Body

The part below the rivet is called the shank or body. This is round in shape.

#3 Tail

The part below its center is called the tail. It is somewhat tapered. It is inserted into holes of two plates, and the head is made by beating its tail. The length of the tail is ¼ D. A rivet is known by its roundness, length, and shape of the head.

How Does A Rivet Work?

In the construction of machines and structures, rivets are very important fasteners. You can attach rivets by drilling, punching, or by inserting them into a hole and distorting the tail. The most common riveting method involves drilling a hole in the component that will be riveted. This is so that it can be more widely used and is much simpler.

To better secure the rivet, it fits in a hole that is drilled about 1.5 mm larger than the rivet’s actual diameter. Once the rivet is in place, the tail appears at the other end with a deformed shape. It is common for the tail of the rivet to unfold or spread when you pound or smash it.

It will increase in size by about 1.5 times its original size. If you pound or pull the tail flat on one end and make a new head on the other end, you can create a dumbbell-sized rivet. The tail then takes the shape of a dumbbell. The joint has been riveted in this manner.

Types of Rivets

There are various types of rivets, including:

  1. Solid rivets
  2. Blind rivets
  3. Drive rivets
  4. Tubular rivets
  5. Split rivets
  6. Flush rivets
  7. Cherry rivets
  8. Self-piercing rivets

#1 Solid Rivets

Solid Rivets

These rivets are made of a single piece of metal and are the most popular type. They are the simplest, most reliable, and oldest types of rivets. Solid rivets are made up of just a shaft and head, which are bent with a hammer or rivet gun. A rivet gun or hammer is used to deform the headless portion on the other end.

These rivets can have either round universal heads or heads that are countersunk by 100°. When dependability and safety are crucial, solid rivets are frequently used. They are employed in numerous fields, including the manufacture of ships, aircraft, and structural steel.

#2 Blind Rivets

Blind Rivets

Blind rivets, also called pop rivets, are used when there is limited access to one side of the joint. They are made of a hollow tube with an internal mandrel that expands when pulled to form a robust joint. To join parts together, manufacturers drill holes in the components and insert blind rivets there.

The mandrel breaks off when the blind end of the rivets expands. Blind rivets can be installed in joints from one side of the part, unlike solid rivets. They become “blind” to the opposing side in this way. It is comparatively simple and quick to apply, just like any other rivet. In the fields of shipbuilding, electronics, and aerospace, it is the most powerful joint.

Several of the typical blind rivets in use are:

  1. Pull-Mandrel Rivets: In their applications, these unique double countersunk blind rivets offer flush surface tightness on both sides. Here, the clamping force is constant because the mandrel head does not separate.
  2. Threaded Rivets: These types of rivets have an internal thread and are entirely anchored on one side. These are also known as threaded inserts. Originally, these were used to fasten deicing boots to aircraft wings.

#3 Drive Rivets

Drive Rivets

They are also referred to as hammer rivets. Drive rivets are a particular type of blind rivet with a short mandrel sticking out of the head. Drive rivets are more frequently used in applications that are intended to be aesthetically pleasing, such as architecture and other fields.

They are also utilized when a strong joint is needed, but access to one side of the joint is restricted. They do not have as strong of a clamping force as many other types of rivets.

#4 Tubular Rivets

Tubular Rivets

These resemble solid rivets but differ in having a hollow center. The standard tubular rivet has a hollow end and a manufactured head on opposite sides. For joining, the hollow end protrudes through each piece.

These types of rivets must be extremely ductile and made of low-strength metals because they must undergo extensive cold forming. As a result, tubular rivets are widely used in industrial settings. They are often used in applications that call for a permanent joint, such as leatherworking.

These are a few of the various types of tubular rivets:

  1. Compression Tubular Rivets: These rivets are made of two parts that interfere with one another when they are being fastened. Their commercial application involves soft materials and calls for aesthetics on both sides of the component.
  2. Semi-Tubular Rivets: These rivets have holes on the field end. Typically, the hole depth is 1.12 times the diameter of the shank. As a result, when the field head is formed, the semi-tubular rivet might feel solid.
  3. Full Tubular Rivets: These rivets have deeper holes than their counterparts. They typically have lower strength than semi-tubular rivets. Even so, softer materials like fabric and plastic are easily penetrated by them.

#5 Split Rivets

Split rivets are formed by cutting a single piece of metal into two pieces. These two pieces are then joined by putting them through a hole already drilled. For joining softer materials like leather, plastic, and wood, they are the best options.

For use in home repairs, split rivets come in sawed or split body varieties. Additionally, they have pointed ends or tips that can pierce the materials themselves. They should not be used in demanding or crucial situations. They are used when a flexible joint is necessary, like making leather goods.

#6 Flush Rivet

Flush Rivets

Like solid rivets, flush rivets differ because their flat head is flush with the surface of the material they are joining. For external surfaces, flush rivets—also known as countersunk rivets—are used to maintain the aesthetic appeal and reduce aerodynamic drag.

This is because it employs both heads and countersunk holes. On the outside of an aircraft, flush rivets are useful for aerodynamic reasons that reduce drag and turbulence. Along with automotive and marine applications, they are frequently used in aircraft construction.

#7 Cherry Rivets

Cherry Rivets

This type of rivet is also known as a pull-through rivet and consists of a metal sleeve with a flared end and is pulled through a pre-drilled hole with a special tool. There are two main applications for cherry rivets, namely aerospace and automotive, in which a strong, permanent connection must be provided.

#8 Self-piercing Rivets

Self-piercing Rivets

It is not necessary to drill or punch holes before using this type of rivet. This is because the end of these rivets has a bevel drill or chamfered poke to pierce the involved components.

Self-piercing rivets produce a gas-tight or water-tight joint by piercing through the top layer of the material while leaving the bottom layer only partially pierced. The rivet’s tail flares and interlocks with the bottom sheet due to an upsetting die, forming a low-profile button.

Materials used in Rivets

For the production of rivets, several types of metals are available. They consist of stainless steel, copper, brass, aluminum, and steel. To meet their needs, manufacturers and designers pick these various materials.

#1 Steel

Applications involving rivets benefit from the use of low-carbon steels. This is because it can secure or fits tightly in its application. Additionally, compared to rigid high-carbon steel rivets, it is much more adaptable and flexible. High carbon steels have a lower moldability and require more material to produce rivets.

#2 Stainless Steel

The stainless steel rivets are highly tough, durable, and deterioration-resistant. These rivets are used in the aircraft, power generation, and locomotive industries. Due to their ability to resist corrosion, these stainless rivets are widely used.

#3 Aluminum

The malleability and lightness of aluminum are well-known qualities. Aluminum is a versatile material that offers a high level of deterioration resistance. Additionally, because aluminum is so malleable, it makes it simple to design complex part layouts.

#4 Copper

In terms of appearance and use, copper is a flexible material. It is extremely effective at transferring heat and electricity. Because copper is such a good conductor of electricity, copper rivets are frequently used in electrical and plumbing appliances.

#5 Brass

Brass is a soft, flexible, and low-friction material. Brass cannot produce sparks because of its characteristics. Brass rivets are the type that works best with gas appliances due to these characteristics.

Types of Riveted Joints

Following are the main types of riveted joint:

  1. Lap joint
  2. Butt joint
  3. Single riveted joint
  4. Double or Chain riveted joint
  5. Chain riveted joint
  6. Zig zag riveted joint
  7. Diamond riveted joint

#1 Lap Joint

Lap Joint

In this type of riveted joint, the ends that fulfill the operation of both elements are such that their surface overlaps slightly. Then the riveting is done through the coincidence hole.

#2 Butt Joint

Butt Joint

In this type of riveted joint, two elements are joined in a straight line from edge to edge. The clamping is built using an outer casing plate. It is then riveted upward through parallel drilled holes.

A butt joint can either use a cover plate or a couple of them. The butt joints have a cover casing, called a single cover butt joint.

In places where hardness and strength are required, two cover plates are normally included, which are then riveted from the upper and lower surfaces of the elements. This is known as the double-cover butt joint.

In addition to the above types, riveted joints can be listed in the following way. It depends on their pouring method:

#3 Single Riveted Joints

Single Riveted Joints

In this type of riveted joint, more than one rivet is fixed along a line, usually in a lap joint, while rows in a butt joint can be visible from both the upper and lower surfaces.

#4 Double-Riveted Joint

Double Riveted Joint

It is also called a double butt joint, when two rows of rivets are involved above a joint or when two rows of rivets are used from both the top and bottom in a butt joint.

#5 Chain Riveted Joint

Chain Riveted Joint

In this joint, the adjusted rows of rivets may be opposite each other as opposed to straight lines.

#6 Zig-zag Riveted Joint

Zig-zag Riveted Joint

Unlike the above types, In the zig-zag riveted joint, the lines here can be staggered and do not complement each other.

#7 Diamond Riveted Joint

Diamond Riveted Joint

As you have seen in the above figure, here, the rivets are arranged in rows that are wide at the ends of the butt and taper at opposite sides, which gives the diamond shape of considerable size. Usually, this type of joint will be found in the butt joints.

Methods of Riveting

Riveting is carried out with the help of dies and backup dies that place a rivet in between them and, by the use of force, the rivet is set into parts to join.

The equal and opposite force distorts the rivet and the tail section of the rivet is turned to head downwards, so the entire rivet sits on the plates. In this process, the rivet’s tail is transformed into a ‘head’ sometimes called a ‘shop head’.

To join the riveting parts, they are drilled with the help of a drilling machine. Clearance is noted when riveting because the diameter of the rivet increases to some extent by pressing.

Normally clearance is considered as per the following:

  • If the diameter of the rivet is, d = 12 to 24 mm, then Clearance is taken as, C = 1.5 mm
  • If the diameter of the rivet is, d = 24 to 48 mm, then Clearance is taken as, C = 2 mm
