Rivet nuts, also known as rivet nuts or riveting caps, are fasteners used in the manufacturing of various metal sheets and pipes. They were developed to solve problems such as the easy melting of welded nuts and stripping of internal threads when tapping thin metal sheets and pipes. Eliminating the need for tapping and welding, they feature strong riveting, high efficiency, and ease of use, and are widely used in the assembly of electromechanical and light industrial products such as automobiles, aerospace, instruments, and furniture.
Rivet nuts can be classified by head shape into flat head and countersunk head, and by thread hole design into through hole and blind hole. The main materials are stainless steel and galvanized carbon steel. Installation requires specialized tools such as pneumatic or manual rivet guns, and the appropriate size must be selected based on the actual sheet thickness.
