A “Washer” is a thin, small circular or disk plate with a hole in the middle used in between the Nut and Bolt. It is used as a support to the fastener. The washer plays a vital role which distributes the pressure of the nut or bolts when it undergoes vibration or uneven surfaces and prevents it from loosening. Washers are usually available in metal, Plastic, Fiber or Rubber. But the role of rubber or Fiber washer is to stop the flow of water from the tap.
1. Locking washer: It keeps a tight grip between the nut and bolt by locking it.
