Spring Washers Type B Flat

The lock washer prevents nuts and bolts from turning, slipping and coming loose because of vibration and torque.
Spring Lock Washers are of many types. The 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.

Spring Washers Type A Square

A Spring washer is a metal ring split at one point and bent into a helical shape. This helps the washer to exert a spring force between the fastener's head and the surface. This keeps the washer firm against the substrate and the bolt thread hard against the nut or substrate thread, creating more friction and resistance to rotation.

A spring washer square has square ends at the split end. Provides much better resistance as compared to a plain washer.
