SS SPRING WASHER
A Spring washer is a metal ring split at one point and bent into a helical shape. This helps the washer to exert a spring force between the fastener’s head and the surface. This keeps the washer firm against the substrate and the bolt thread hard against the nut or substrate thread, creating more friction and resistance to rotation. A spring washer square has square ends at the split end. Provides much better resistance as compared to a plain washer.
