1/2 STEEL SPLIT LOCK WASHER1/2 STEEL SPLIT LOCK WASHER 510300, 100 PER BOX A split washer is 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 your part, which maintains the washer hard against that part and the bolt thread hard against the nut, creating more friction and resistance to rotation. Thus when tightening the bolt, it will resist turning because of the force being created by the lock washer design. Available in small quantities, they are also boxed in one and five pound containers, depending on their size. Metric and stainless steel sizes are also available.
