Description :-

Spring washers also called split lock washers, provide a vibration resistant function, they consist of ring split at one point and bent into a helical shape, this causes the washer to exert a spring force between the fastener's head and the bearing face which maintains the washer hard against the face and the bolt thread hard against the nut or threaded hole, creating more friction and resistance to rotation. Spring washers are hotdip galvanised to increase the longevity and durability of the material, spring washers are single coiled, double coiled and triple coiled.
