Metal Washers

This is Nuts Bolts Washers India, a world known manufacturer and suppliers of Washers in all metals in ferrous and Non Ferrous and even in alloys. A company exclusively engaged in manufacturing and exporting quality Washers from more than a decade. This is not just a fastening or washer manufacturing firm but a one door arrangement for all your requirements for any kind of Washers.

A washer may be a thin or thick plate (typically disk-shaped) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener. Other uses are as a spacer, spring (belleville washer, wave washer), wear pad, preload indicating device, and locking device. Rubber washers are also used in taps (valves) where they form the seal that shuts off the flow of liquid or gas. Rubber or silicone washers may also be used to reduce vibration when fastening fans to computer cases. Washers usually have an outer diameter (OD) about twice the length of their inner diameter (ID).

Washers are usually metal or plastic. High quality cap screws require hardened steel washers to prevent the loss of pre-load due to Brinelling after the torque is applied. Rubber or fiber gaskets used in taps to stop the flow of water are sometimes referred to colloquially as washers; while they may look similar, however, washers and gaskets are usually designed for different functions and made differently.
