The principle of the riveting nut

The pressure riveting nut is a nut applied to a thin plate or sheet metal, round in shape, with embossed teeth and a guide groove at one end. The principle is to press into the preset hole of the sheet metal through the embossing teeth. Generally, the aperture of the preset hole is slightly smaller than the outer diameter of the embossing nut. Through the pressure, the pressing nut teeth squeeze into the plate, resulting in plastic deformation of the periphery of the hole, and the deformation is squeezed into the guide groove, thus producing the effect of locking.
