C WASHER FOR SHANK

A schank is the long, narrow part of a tool connecting the handle to the operational end. A shank is frequently used with a faucet or dispensing control knob or handle. The unthreaded part of the shaft of a bolt is also called the shank.

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.
