A rivet is a short cylindrical bar with a head integral to it. The cylindrical portion of the rivet is called shank or body and lower portion of shank is known as tail, as shown in Fig. The rivets are used to make permanent fastening between the plates. The riveted joints are widely used for joining light metals.
The riveted joints are permanent fastenings used to joint on connect two or more sheet metal plates together, the joint must be leak proof and strong to prevent leakage and failure. The rivets are made of low carbon steel or nickel steel, brass, aluminum or copper by the process of either cold heading or hot forging. Riveted joints are used in the structural work, ship building, bridges, tanks and boiler shells.
