The principle is to press the embossing teeth into the preset holes of the sheet metal. Generally, the aperture of the square preset holes is slightly smaller than the embossing teeth of the pressure riveting nut. The flower teeth of the pressure riveting nut are forced into the plate by pressure. The periphery of the hole is plastically deformed, and the deformation is squeezed into the guide groove, which produces a locking effect and is not easy to fall off. It is mostly used on metals that require high fastening. less
