Lifespan of self clinching fasteners1. Be sure to comply with the mounting holes of the specified size for each pressure riveting fastener;
2. Make sure that the bottom end (or guide groove) of the riveting fastener is in the placement hole before applying the placement force. Developed to solve the shortcomings of metal sheets and thin tubes that weld nuts are easy to melt, and tapping internal threads is easy to slip. It does not need tapping internal threads or welding nuts.
Types of flare-in nuts: flat head, small head, hexagonal and half hexagonal rivet nuts, with through holes, with blind holes, with knurling and without knurling.
3. Ensure that the fastening force is applied between parallel surfaces. The fastening force is to prevent twisting when using fixed fasteners and during assembly.
4. Ensure that sufficient seating force is applied to fully engage the snap ring along the entire perimeter and to make the boss surface just in contact with the board.

Contraindications for the construction of rivet nut fasteners:
1. Do not install carbon steel pressure riveting fasteners or stainless steel pressure riveting fasteners before the aluminum plate is anodized or surface treated.
2. Do not remove the surrounding burrs before installing the pressure riveting fasteners --- because removing the burrs will consume the metal used to fasten the fasteners and the plate.
3. Do not install pressure riveting fasteners closer to the Z shor

Self clinching nuts are mostly found in machinery, electrical appliances and buildings, etc. The general raw material is metal or plastic, in a cylindrical shape, and the surface is engraved with high and low grooves called threads. The thread is a spiral inclined surface coiled around the side of the rivet nut, so that the rivet nut can use the screw mechanism to close the rivet nut cap or other objects. The inner side of these objects has threads corresponding to the rivet nut, called internal thread. Generally, the internal rivet nuts of rivet nuts or other objects need to be processed separately, but there is a kind of rivet nuts called self-tapping rivet nuts, which can cut internal threads on soft objects, so no extra processing is required. processing. 

The main function of the rivet nut is to join two objects, or to fix the position of an object. Rivet nuts can generally be removed or re-tightened at will without compromising their efficiency, provide greater strength than nails, and can be reused.
Generally, the diameter of the top of the rivet nut is relatively large, and the most common ones are round, square or regular hexagonal, and there are also flare-in nuts. If the top is a regular hexagon, you can use a wrench to turn the rivet nut. If the top is round, there will be grooves on the front of the top, so you can use the corresponding rivet nut driver to turn the rivet nut. The common grooves are one-shaped, cross-shaped and square, and there
