washer
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 are usually metal or plastic. High-quality bolted joints require hardened steel washers to prevent the loss of pre-load due to brinelling after the torque is applied. Washers are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminium surfaces. They may also be used in rotating applications, as a bearing. A thrust washer is used when a rolling element bearing is not needed either from a cost-performance perspective or due to space restraints. Coatings can be used to reduce wear and friction, either by hardening the surface or by providing a solid lubricant (i.e. a self-lubricating surface).
The origin of the word is unknown; the first recorded use of the word was in 1346, however, the first time its definition was recorded was in 1611.Rubber or fiber gaskets used in taps (or faucets, or valves) as seal against water leaks are sometimes referred to colloquially as washers; but, while they may look similar, washers and gaskets are usually designed for different functions and made differently.

How or where can I buy a washer for an antique faucet stem?
I have an antique sink and was able to remove the stem. It had a work out washer on the end of it. Is it possible to find these washers today? The ones I had were too small and this one also was not flat.- Kimberly

Replace tap washer!
I've done this on so many taps without problem but... I just can't seem to see how to get at the guts of this John Sydney tap.

How to change a washer in the shower
Hi all, I need to change a washer on a leaking tap in my shower, but I can't figure out how to get the tap out to change it. I can unscrew the base of the tap from the wall and get it out from the wall a little way and I can see where I would need to get a spanner/wrench onto the brass piece...- Deleted member 117499
