DRIVE PIN GLASS WASHER BRUSHES

Pins are used to hold together assemblies to fasten two or more common components to each other and serving as hinges, axles, aligners and pivots with stops that maintain a positive limit upon the movement of components within machinery and mechanical components.

A washer is a thin plate (typically disk-shaped, but sometimes square) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Other uses are as a spacer, spring (Belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration (rubber washer). Spring washers, which have axial flexibility are used to prevent fastening or loosening due to vibrations. Locking (lock) washers prevent fastening or loosening by preventing unscrewing rotation of the fastening device.
