Our factory specializes in producing 304 stainless steel nylon hexagonal flange locking nuts, which are formed by SUS304 cold heading. The flange surface is integrated with the hexagon, and nylon anti loosening rings are pressed into the inside. After tightening the nut, the nylon ring is locked with the bolt thread, effectively preventing loosening and can be reused multiple times. Replacing flat pads with flange surfaces increases the contact area and disperses pressure.
