The included washers help create a tighter installation for increased strength and support. Copper rivets and burrs feature a cylindrical shape with a head on one end and a tail on the other. The head rests on the surface of the material, while the washer and tail are hammered to secure the rivet, providing a sturdy and reliable fastening solution for various applications. Simple hammer-in installation: use a hammer to set the washer, trim excess pin length with pliers, and flatten or round the tail using a suitable tool. Some rivets may require a hole punch to prepare the material before installation.
