Pressure rivet bolts, also called pressure rivet screws, pressure rivet screws. It is a fastener used for riveting, a standard part. Riveting bolts are generally used in electronic machinery and equipment, sheet metal industry products, metal stamping or copper, aluminum, plastic and other materials, and the end of the riveting bolt with threads needs to be extruded into the product material matrix by stamping or other means

It is a new type of fastener applied to thin sheet metal or sheet metal. Its principle is to press into the preset hole of sheet metal through embossing teeth, the aperture of the general preset hole is slightly smaller than the pressed-in outer diameter of the press-riveting screw, and the outer diameter of the press-riveting screw is pressed into the plate through pressure to cause plastic deformation of the periphery of the hole, and the deformed object is squeezed into the guide groove, so as to produce the effect of locking. Pressure riveting screws are divided into fast-cutting steel pressure riveting screws, stainless steel pressure riveting screws and copper and aluminum pressure riveting screws from the material, which should be used in different environments. Specifications are usually from M2 to M6. There is no unified national standard for pressure riveting screws, only industry standards. It is often used in electronics, communications, electrical appliances, chassis, cabinets, sheet metal and other industries.
