Rivets are an effective way of securing hard items, such as sheet metal, to one another. There are many types of rivets available for different applications and industries, including bifurcated rivets.
Bifurcated rivets are also referred to as split rivets. They differ from other rivets because they have a divided end. This divided end, once inserted into the material being adhered, splits apart to create a strong, secured connection. They can be purchased with either a countersunk head, which creates a smooth surface after installation, or an oval head, which leaves a small domed portion above the material's surface.
Place the rivet in the hole with the divided end, or shank, facing the installer. Hold the top, or head, of the rivet securely and heat the shank end with a welding torch. As it is heated up, hit it with a ball peen hammer to spread the shank's two divisions outwards until it has swollen and is securely attached to the material being riveted.
Any use of a welding torch should be done by a trained professional. The heat generated by the torch can be dangerous and cause major injury.
