Self clinching nuts are mechanical fasteners that secure the nut to the sheet by forming threads in the sheet. However, rivet nuts are not suitable for all material plates, especially stainless steel plates and medium carbon steel plates.

First of all, the hardness of stainless steel plate and medium carbon steel plate is relatively high, and it is not easy to deform. The function of the pressure rivet nut is to form a tight connection between the nut self clinching fasteners and the plate by forming threads on the plate. However, if the hardness of the plate is too high, the thread cannot be formed or the formed thread is not firm, which will affect the fixing effect of the nut.
Secondly, the strength and toughness of stainless steel plate and medium carbon steel plate are also relatively high, and it is easy to form cracks and deformation. When using rivet nuts to fix the sheet, stamping is required on the sheet, which may cause certain deformation and stress concentration on the sheet, resulting in cracks and deformation of the sheet, affecting its service life and mechanical properties.
In addition, the surface of stainless steel plate and medium carbon steel plate is usually relatively smooth, which is not easy to generate friction and friction heat, which will also affect the fixing effect of the rivet nut. Therefore, when using rivet nuts, they should be selected according to the material and hardness of the plate to ensure the fixing effect and servic
