A rivet is a kind of metal product used for connecting and fixing objects. It usually has a cap-shaped head at one end and a smooth cylindrical rod at the other end. It is mostly made of metals such as steel, aluminum, and copper. When in use, the rivet is passed through the holes of the objects to be connected, and then the rod is deformed by external force to form a rivet head at the other end, thus closely connecting the objects together. Rivet connections have the advantages of high strength, good sealing performance, and strong vibration resistance, and are widely used in many fields such as aerospace, automotive manufacturing, and construction.
