Self clinching nuts, also known as rivet nuts, are self-clinching nuts, which are a kind of nuts applied to thin plates or sheet metals. They are round in shape, with embossed teeth and guide grooves at one end. The principle is to press the embossing teeth into the preset holes of the sheet metal. Generally speaking, the aperture of the preset holes is slightly smaller than the embossing teeth of the rivet nut. The periphery of the hole is plastically deformed, and the deformation is squeezed into the guide groove, and then the locking effect occurs.
Pressure riveting means that during the riveting process, under external pressure, the pressure riveting parts cause the base material to undergo plastic deformation, and then squeeze into the special prefabricated grooves in the riveting screw and nut structure, and then complete the reliability of the two self clinching fasteners. There are two kinds of non-standard nuts for pressure riveting, one is pressure riveting nut column and the other is pressure riveting nut. If this riveting method is used to complete the connection with the base material, this riveting method generally requires that the hardness of the riveted parts be greater than that of the base material.
Ordinary low-carbon steel, aluminum alloy plate, and copper plate are suitable for crimping standoffs. For stainless steel and high-carbon steel plates, because of their relatively hard materials, special high-strength standoffs are required, which are n
