It is round in shape, with embossed teeth and guide grooves on one end. The principle is to press the embossed teeth into the preset hole of the sheet metal. Generally speaking, the aperture of the preset hole is slightly smaller than the embossed teeth of the self-clinching nut. The pressure makes the teeth of the self-clinching nut squeeze into the plate to make the periphery of the preset hole plastically deformed, and the deformed object is squeezed into the guide groove, thereby producing a locking effect.
