Washers

Washers are a quintessential component in countless applications. Typically thought of as little more than a simple piece of hardware, washers can make all the difference in the longevity, functionality and durability of the overall application. Based on the unique physical qualities of a washer, such as material, shape and composition, the properties and operation of the application can be enhanced just by selecting the proper washer.

Washers are used to distribute the load of a fastener, provide spacing or tension, serve as a locking mechanism, provide insulation or dampen vibration, or add spring-back or defection properties to an application. The most common washers are thin, circular and disk shaped. A hole is most commonly placed in the center of the disk. The overall diameter of the washer dictates the exterior or outside measurement while the diameter of the hole determines the interior, or inside measurement. Thickness of the washer also affects the fit and functionality of the washer within its application.

A range of standard washer varieties include:
  • Flat Washers: The most commonly used in treaded fastener applications
  • Belleville Washers: Conical shape, provide a pre-load flexibility
  • Wave Washers: Curved height to provide a deflection within a setting
  • Specialty Washers: Non-standard washers, usually with an non-circular inside or outside measurement.

As material greatly affects the capabilities and properties of each washer, a complete selection of the most common and qualities washer materials include:

  • Aluminum
  • Stainless Steel
  • Copper
  • Brass
  • Plastic
  • Teflon
  • Fibre
  • Mica
