Riveted joints
Riveted joints are the joints that are perpetual, comprising of fundamentally two parts that are controlled together by the bolt, head at the top, and tail (barrel-shaped stem) at the base.

As the name suggests, in this type of joint, two-member slightly overlap each other. These two members joined together through the coincident holes.
2. Butt Joint
In this type of joint straight edges of the members are joined by using the cover plate. Clamping is done by using this cover plate. ( as shown in the figure )
An Overview of Rivets
In a nutshell, a rivet is a mechanical fastener or connector with a head and tail at opposite sides. It has a head, a smooth cylindrical body, and a tail that looks more like a metallic pin.
Materials Used for Rivets
There are several metal materials for manufacturing rivets. They include steel, copper, brass, aluminum, copper, and stainless steel. Designers and manufacturers choose these different materials to satisfy their needs.
Different Types of Rivets Available for Manufacturing
There are several different types of rivets available. However, they are broadly divided into the following categories.
What are Rivets Used For?
Rivet’s primary purpose is to ensure a firm and reliable tightening of two or more metallic or wooden materials. When you do this, you have a joint stronger than that of a screw with the same diameter.
Conclusion
Rivets are a better substitute for screws, bolts, and nuts. They prove more efficient and reliable than all other connectors. Today, different types of rivets have various purposes. This is a result of the dynamic nature of machines and structures. However, you have to choose suitable metal rivets for your applications to get the best results.
