[0002] Rivets are nail-shaped objects used to connect two parts with through holes and a cap at one end. In riveting, the riveted parts are connected by using their own deformation or interference. There are many types of rivets, and they are not restricted by form. One of the most commonly used rivets is the stainless steel solid rivet. Usually, during the production and processing of this type of rivet, it is necessary to self-drill a hole on the end of the rivet away from the top cap.
