Description
The lock washer prevents nuts and bolts from turning, slipping and coming loose because of vibration and torque.
The washer has sharp edges that dig into the nut as well as mounting surface in order to prevent rotation in the counter clockwise direction.
Spring Lock Washers are of many types, most common one being the helical split washer. 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.
