　   A brief introduction to self-clinching nuts, Rose riveting nuts and riveting nuts

Self-clinching nuts, also known as rivet nuts, are a type of nut used in sheet metal or sheet metal. They are circular in shape and have embossed teeth and guide grooves at one end. The principle is through the embossing teeth pressed into the sheet metal preset hole, generally speaking, the aperture of the preset hole is slightly less than the embossing teeth of the riveting nut, through the pressure of the riveting nut extrusion into the plate so that the surrounding of the preset hole plastic deformation, deformation is squeezed into the guide groove, and then the locking effect.

Pressure riveting refers to in the process of riveting, under external pressure, pressure riveting parts to make the matrix material plastic deformation, and squeeze into the riveting screw, nut structure in the special precast groove, and then complete the two parts of the reliable connection method, pressure riveting non-standard nuts have two kinds, one is the pressure riveting nut column, one is the pressure riveting nut. If this riveting method is used to complete the connection with the base material, the hardness of the riveted parts is generally required to be greater than the hardness of the base material.

Ordinary low carbon steel, aluminum alloy plate, copper plate for crimping pressure riveting nut, for stainless steel and high carbon steel plate because of the material is hard, needs a special high strength pressure riveting nut, not only the price is very high, meet difficulties and pressure, the pressure is not reliable, simple after pressure to fall off, manufacturers in order to guarantee the reliability, often demand beside the nut column surface and welding, good manufacturability owe, Therefore, there is pressure rivet nut column and pressure rivet nut sheet metal parts as far as possible do not choose stainless steel. This is also the case with riveting screws and riveting nuts, which are not suitable for use on stainless steel plates.

A riveting nut is a riveting nut that is formed by the plastic deformation of the riveting screw or nut. The riveting nut is a riveting nut that is formed by the plastic deformation of the riveting nut. Commonly used ZRS and so on is to choose this type of riveting to complete the connection with the base material. The riveting process is relatively simple, the connection strength is low, generally used in the fastener height is limited, and accept the torque is not large.

Pull riveting refers to in the process of riveting, riveting parts in the effect of external tension, plastic deformation, its deformation position is generally in the special planning of the position, by the deformation of the base material to end the reliable connection. The commonly used riveting nut is used to complete the connection with the base material. Pull riveting uses special riveting guns for riveting, which are often used in situations where the device space is small and universal riveting tools cannot be used, such as closed pipes.
