Fastener knowledge: principle and product advantages of pressure riveting nuts

The so-called pressure riveting nut can also be called a riveting nut or a self-fastening nut. It is mainly used for a kind of nut on a thin plate or sheet metal. Its shape is round and one end has embossed teeth and guide grooves.

Precautions when installing pressure riveting nuts: In the use of pressure riveting studs, although the installation method and principle have been determined, the pressure riveting studs still need special riveting equipment to operate, which is also a guarantee for the pressure riveting screw It is an indispensable factor for the column to maintain stable working performance after installation. During installation, the heads of the riveting press and the pressure riveting studs should be vertically balanced and pressed down evenly. (Guide: Briefly describe the application of anchor bolts)

The working principle of the pressure riveting nut: the preset hole of the sheet metal is pressed into the sheet metal through the embossing teeth. Generally, the diameter of the square preset hole is slightly smaller than the embossing teeth of the pressure riveting nut. The pressure of the pressure riveting nut The teeth squeeze into the plate to cause plastic deformation of the periphery of the hole, and the deformation is squeezed into the guide groove, thereby producing a locking effect. Pressure riveting nuts are divided into quick-cutting steel pressure riveting nuts S type, stainless steel pressure riveting nuts CLS type, stainless steel pressure riveting nuts SP type and copper and aluminum pressure riveting nuts CLA type. They should be used in different ring environments. .

Five advantages of pressure riveting nut products:

1. Keep the back of the board completely flush;

2. Small and exquisite, suitable for all electronic or precision equipment;

3. High torque resistance;

4. Convenient equipment, just simple pressure riveting;

5. Serialization of specifications can meet a variety of design requirements.
