Product ID : FSN-WSH-2

Spring washers have axial flexibility and are used to prevent fastening or loosening due to vibrations by creating a 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 substrate, which maintains the washer hard against the substrate and the bolt thread hard against the nut or substrate thread, creating more friction and resistance to rotation.
