Washer is a loophole (usually in the middle) in the sheet (usually circular) that is usually used to allocate load thread fasteners. Other uses are as spacers, springs (Belleville gaskets, wave gaskets), wear-resistant gaskets, pre-display devices, locking devices. Rubber gaskets are also used in faucets (valves) to cut off flowing liquids or gases. Rubber or silicon gaskets can also be used to reduce fan vibration. Usually the outer diameter of the gasket is about two times that of the inner diameter.
