Knowledge sharing from a professional manufacturer of self-tapping nuts – The working principle of stainless steel nuts. Stainless steel nuts are made from high-quality stainless steel wire; their cross-section is diamond-shaped, and they have threads formed by mechanical coiling into a spring-like shape. The diameter of the stainless steel screw sleeve is larger than that of the screw hole; during installation, the screw sleeve compresses and tightens, and once installation is complete it returns to its original shape, thereby fixing the stainless steel screw sleeve permanently within the screw hole. Due to its larger diameter, the threads have a larger contact area, making them stronger than the original threads. Furthermore, the elastic coils of the thread sleeve allow for independent adjustment, thereby ensuring maximum surface contact with individual threads in the substrate. This results in a more even distribution of loads, reduces stress and fatigue concentration, maximizes thread strength, and enhances the reliability and lifespan of the fastening system. The use of stainless steel prevents corrosion under normal environmental conditions, reduces electrical erosion during threaded assembly, and further extends the lifespan of the assembly; therefore, such coatings can generally be used at temperatures ranging from -320 to +800 degrees.
