The self-fastening nut is a kind of nut used on thin plates or sheet metal. The shape is round, with embossed teeth and guide grooves at one end. The principle is to press the embossing teeth into the preset holes of the sheet metal. Generally speaking, the aperture of the preset holes is slightly smaller than the embossing teeth of the rivet nut. The flower teeth of the rivet nut are squeezed into the plate by pressure to make the preset The periphery of the hole is plastically deformed, and the deformed object is squeezed into the guide groove, thereby producing a locking effect.

Installation matters of rivet nut:

The hardness of the low carbon steel plate should be less than 70RB, and the hardness of the stainless steel plate should be less than 80RB.

It is suitable for plates of various thicknesses, with a small thickness of 0.8mm. The tail number Z corresponding to the size A can be determined according to the thickness of the plate and the nut specification when using it. The user selects and orders the thickness of the plate according to the tail number in the table.

If the stainless steel rivet nut is tightened too tightly, the interface will be rusted, which is not conducive to disassembly. It is recommended that when screwing the nut, screw it by hand first, and then use a spanner to twist it half a turn to one turn after it reaches the end. When installing car tires, the screws should not be tightened too tightly, otherwise, the screws may be deformed and affect the fixing effect. On the same tire, the tightness of each screw must be even, and no individual screws can be tightened very tightly. Otherwise, it will affect the tire's driving. In severe cases, the screws may be broken due to uneven force.
