We are offering ms washers. A washer is a thin plate (typically disk-shaped) with a hole that is normally used to distribute the load of a threaded fastener, such as a screw or nut. Washers are available in all sizes.
We are offering Spring Washers. Spring 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 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. Available in all sizes.
