The installation of the pressure riveting nut is exquisite. If the installation method is not correct, the riveting will not be firm after the pressure riveting. For example, one of our customers reported that the nut would fall off after riveting. Our technicians found that many customers hit it with a hammer or other impact methods, because the installation method of the riveting nut will cause pressure. The uneven force of the rivet nut seriously affects the riveting effect. It looks like it is pressed in on the surface, but in fact, the flower teeth of the rivet nut are not riveted with the plate at all, so it is definitely not riveted.
