Pressure rivet nut, also called rivet nut, self-fastening nut, is a nut used on thin plates or sheet metal. It is round in shape and has embossed teeth and guide grooves on one end. The principle is to press into the preset hole position of the sheet metal through embossed teeth. Generally speaking, the aperture of the preset hole is slightly smaller than the embossed teeth of the rivet nut. The teeth of the rivet nut are squeezed into the plate through pressure to make the preset hole position. Plastic deformation occurs around the hole, and the deformed object is squeezed into the guide groove, thereby producing a locking effect.

Rivet nuts, used in various types of metal sheet, pipe and other manufacturing industry fastening field, widely used in automobiles, aviation, railway, refrigeration, elevators, switches, instruments, furniture, decoration and other mechanical and electrical and light industrial products assembly.
