  • Asiamet is a leading manufacturer, suppliers in India. 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.

What is a Special Washer?

Special washers have the same purpose as traditional standard washers however they are defined by their irregular shape being either non-circular on the inside or outside. Standard washers have two main purposes to distribute the pressure of the nut evenly over the surface, so that the surface isn’t damaged, and. To ensure that the nut is pressed against a smooth surface reducing the chance that it’ll gradually loosen because it’s in contact with an uneven surface.
