Spring lock

Listing ID #4224354

Any washer designed to prevent a bolt or screw from turning and loosening. Types include Belleville, split and toothed washers. A Spring Washer is a ring split at one point and bent into a slightly helical shape. This allows the washer to exert a spring force between the bolt or screw head and the substrate, helping to prevent the bolt from turning and loosening due to vibration.
