Anti-loosening nutThe anti-loosening principle: The top of the conventional 60-degree tooth tip features a 30-degree wedge. This structure, when tightened with a nut, generates greater friction compared to traditional methods, resulting in superior anti-loosening performance. There are four methods to prevent the loosening of anti-loosening nuts: preventing friction loosening, mechanical nut loosening, rivet mandrel loosening, and structural loosening.

A limited size must be fixed for manufacturing anti-loose nuts, as the parts must be within a reasonable size range. The actual dimensions after manufacturing fall within the fixed range of large and small sizes. The allowable variation in size is called size tolerance, or simply tolerance.

Stainless Steel Lock Nuts, Performance Grades: 45, 50, 60, 70, 80

Anti-loosening nuts are mainly divided into Austenitic (18%Cr, 8%Ni) types, which have good heat resistance, corrosion resistance, and weldability. A1, A2, A4.

Martensitic, 13% Cr has poor corrosion resistance, high strength, and good wear resistance. C1, C2, C4 ferritic stainless steels. 18% Cr has better forgeability and superior corrosion resistance to martensitic steel. Currently, imported materials on the market are mainly Japanese products. Mainly categorized by grade as SUS302, SUS304, and SUS316.
