Self Clinching Nuts are also called rivet nuts, self clinch nuts, and self-fastening nuts. It is cylindrical in shape, with embossed teeth and guide grooves on one end. It‘s a special nut mainly used on thin plates or sheet metal.

Its principle is to press the embossing teeth into the preset holes in the sheet metal, and use the pressure to squeeze the teeth of the Self Clinching Nuts into the plate, causing plastic deformation around the preset holes, and the deformed objects are squeezed into the guide grooves , thereby producing a locking effect. Generally speaking, the diameter of the preset holes is slightly smaller than the embossing teeth of Self Clinching Nuts.

They are usually available in sizes from M2 to M12. It is available in free cutting steel S type, stainless steel CLS type, stainless iron SP type, as well as copper, aluminum CLA type and other materials.
