Hardened HRC 26-45 Steel Black Finish 5/8 Inch Structural Flat Washer F436
Hardened HRC 26-45 steel black finish 5/8 inch Structural Flat washer F436
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). Washers often have an outer diameter (OD) about twice their inner diameter (ID), but this can vary quite widely.
