Rivets and Types of Riveted Joints

It is almost impossible that huge structures such as bridges, skyscrapers, airplanes, locomotives, etc., would be built without the inclusion of these small but strong integrated mechanical devices. Rivets not only allow these structures to become huge but also ensure equal strength and endurance to withstand many different natural and emergent challenges.

Originally rivets are tools such as bolts, made of tensile metals, inserted through parallel holes drilled across the joining members and on the other side to produce true and permanent firm locking joints. Are perforated by

Let us discuss and learn various types of rivet joints popular with structural engineering. A rivet is a small cylindrical strip in which ahead is integrated. The cylindrical part of the rivet is called the shank or ingot.

The bottom part below the shanks is called the tail. The semi-hemispherical part at the top is called the head.


Rivets are used to make permanents fastening between plates such as structural work, shipbuilding, bridges, tanks, and boiler cans. We take two plates; both of these plates are either placed in front of each other or placed on top of each other. A hole is made on both plates, and a rivet is inserted between the holes of the plates.

The rivets are inserted in such a way that the head is at the top and the tail is at the bottom. After the rivet is inserted, the tail is tilted, and the tail is shaped ahead, creating a joint between the two plates called the riveted joint.

Types of Riveted Joints:

Types of Riveted Joints

Based on the arrangements of the plates, Riveted Joints are classifieds into two types:

  • Lap Joint.
  • Butt Joint.

#1. Lap Joint

Lap is when two plates are placed above or below each other. When two plates are folded under or above each other, this type of joint is called a lap joint.

Riveted Lap joints are made by placing two plates above or below each other, creating a hole in these two plates & fixing the rivet inside the holes of the two plates, and hitting the rivet’s tail with a hammer.

#2. Butt Joint

In the butt joint, both plates are combined by placing the plates on each other or on each other. The two plate touches each other but does not overlap each other. To join two plates side by side, cover plates are used, which typically have a thickness less than the thickness of the main plate.

The butt joint is placed on either side of the main plate and on both sides of the plate by covering the plate, and holes are made at the joint of the main plate, and a rivet is inserted into the cover plate and each hole of both plates.

Cover Plates Used, the Butt Joints Is Further Divided into Types:

Based on the number of cover plates used, the butt joint is further divided into two types:

#1. Single Strap Butt Joint

In butt joints, if only one cover plate is used on top of the main plate, then this type of butt joint is called a Single Strap Butt joint.

#2. Double Strap Butt Joints

In the butt joint, if only two cover plates are used on the top of the main plate, then this type of butt joint is called Double Strap Butt Joint.

Lines of Rivets Used the Rivets Joints Are Classified into Different Types:Single and Double Riveted Joint

Based on the number of lines of rivets used, the rivets joints are classified into a different types:-

#1. Single Riveted Joint

If a single line of the rivet is inserted between the two plates, then it is called a Single Riveted Joint. Single Riveted Joints can be of Lap type or Butt Type.

#2. Double Riveted Joint

If two lines of rivet are inserted between the two plates, then this type of joint is called a Double Riveted Joint. Double Riveted Joints can be of Lap type or Butt Type.

In Double Riveted Lap Joints, there are two lines of rivets between the main plates used to create a joint. In Double Riveted Lap Joints, there are two lines of rivets in each main plate and cover plate combinations.

Based on the Arrangement of Rivet Riveted Joints:

Chain and Zig-Zag Type Riveted Joint

Based on the arrangement of rivets, Riveted Joint are classified into two types:

#1. Chain Type Riveted Joint

In a multi-line riveted joints, if all lines of rivet are placed adjacent to each other in the same transverses line, then it is called Chain Type Riveted Joints.

#2. Zig-Zag Type Riveted Joint

In a multi-line riveted joints, if the lines of rivet are arranged in zig-zag type, then it is called a Zig-Zag Type Riveted Joints.

Type of Failures in Riveted Joints:

  • Crushing failure of plates.
  • Shear failure.
  • Tearing of plate occurring in the margin area.
  • Tensile failure of plates.
  • Shear failure occurring in the margin area.

Advantages of Riveted Joints:

  • It can be used for non-ferrous metals.
  • Quality inspection of a riveted joints is very easy and cheap.
  • It is more reliable.
  • At the time of dismantling, the part joined have less damage as compared to welded parts.
  • The parts which are joined by rivets joints do not have any damage due to heat, as in the case of weldings joints.

Disadvantages of Riveted Joints:

  • The cost of labor is high.
  • Due to holes, plates become weak.
  • Overall cost, including labor costs, is high relatively.
  • Stress is concentrated near the holes.
  • The overall weight of the joints parts increases.
  • Riveting creates more noise.

Applications of Riveted Joints:

  • These joints are most commonly used for fastenings sheets & shaped rolled metals.
  • Riveted joints are used to join metal that cannot be welded or heated, for ex – thin-walled parts made of sheet materials in aircrafts construction.
  • They are used for the manufacturing bus & trolleybus bodies to create a heavily loaded joint.
  • They are also used for joinings components in aircraft, ships, boilers, as well as other enclosures.

Frequently Asked Questions (FAQ)

Types of Riveted Joints

There are two main types of riveted joints: lap joints and butt joints (fig. 16.33). In lap joints, the components to be joined overlap each other, while for butt joints, an additional piece of material is used to bridge the two components to be joined, which are butted up against each other.

Single Riveted Lap Joint

The efficiency of a riveted joint is equal to the strength of the joint divided by the strength of the un riveted plate, expressed as a percentage.

Double Riveted Lap Joint

Double riveted joint if two lines of rivets are inserted between the two plates, then this type of joint is called a double riveted joint. Double riveted joints can be of lap type or butt type.

Advantages of Riveted Joints

  • It is more reliable.
  • It can also be used for non-ferrous metals.
  • Parts assembled by riveted joints do not have any thermal after effects.
  • Its quality inspection is easy and cheap.
  • When parts are dismantled, riveted parts have less damage compared to welded parts.

Applications of Riveted Joints

  • It is used where we have to avoid after-thermal effects, as in the case of welding.
  • Used for metals that have poor weldability.
  • Used for heterogeneous materials like asbestos friction lining and steel.
