Rivet nuts are very common fasteners and have a wide range of uses. Let's briefly talk about its uses and specifications:
If the nut of a certain product needs to be installed on the outside, and the space inside is small, it is impossible to let the indenter of the riveting machine enter for pressure riveting and methods such as sprouting cannot meet the strength requirements, then pressure riveting and expanding riveting are not feasible. Blind riveting must be used. It is suitable for the fastening field of various thickness plates and pipes (0.5MM-6MM). The use of pneumatic or manual riveting guns can be rivetted at one time, which is convenient and firm; it replaces the traditional welding nut to make up for the shortcomings of thin metal plate, thin tube welding, and welding nuts are not smooth.
The specifications of rivet nuts in the national standard are M3, M4, M5, M6, M8, M10, and M12. In fact, M6 and M8 are recommended, because small threads can be directly tapped on the base material for connection. If the thread is large, the weight of the bolt will greatly increase. The increase in connection strength is limited, that is, the matching is unreasonable.
It can be seen from the above that rivet nuts can be widely used on aluminum alloy substrates of different thicknesses or steel plates with thicknesses of 1-2.5mm. In particular, the connection of steel rivet nuts to aluminum alloy components eliminates the cumbersomeness of embedding steel plates inside, and its manufacturability is significantly improved.
