Washers come in a wide variety of designs and within those individual designs are a range of materials, dimensional variations and finishes. Many can be used either under the head of the fastener, bolt or screw, or under the nut. Many can be encapsulated as an assembly on a screw or bolt or occasionally with a nut. Most washer sizes will be designated by the diameter (size) of the fastener with which they are to be used.

Basic washers are employed to

  • spread the clamp load over a larger surface area
  • cover an oversize or elongated hole
  • reduce the friction of the rotated component
  • protect the work piece surface from damage by the rotated component
  • provide a locking or vibration resistant function

Specialist washers have been designed to perform particular functions in particular types of applications. These may be locking, load spreading, decorative, tension indicating, sealing, or a combination of these functions.
