Many things around us need to use rivet nuts, nails, and other confinement tools, but do you know the principle of carbon steel rivet nut and other rivet nuts?

Compression riveting nut is also called the riveting nut, the self-fastening nut is a kind of nut applied to the thin plate or sheet metal, the shape is round, one end has embossed teeth and guides groove.

The principle is to press embossed teeth into the pre-set holes of the sheet metal. Generally, the hole diameter of the square pre-set holes is slightly smaller than the embossed teeth of the pressure riveting nut. The flower teeth of the pressure riveting nut are pressed into the plate to cause the hole Plastic deformation occurs at the periphery, and the deformation is squeezed into the guide groove, thereby producing a locking effect. Pressure riveting nuts are divided into S-type quick-cutting steel pressure riveting nuts, stainless steel pressure riveting nuts CLS type, stainless iron pressure riveting nuts SP type, and copper and aluminum pressure riveting nuts CLA type. They should be used in different ring environments. . The specifications are usually from M2 to M12. There is no unified national standard for riveting nuts, and they are often used in cabinets and sheet metal industries.

Of course, the same principle applies to flat head rivet nut .
