Washers are thin disks used to spread the load in nuts and screws or prevent leaks. Manufacturers also utilize them as spacers, preloaded indicated products, and wear pads. Usually, washers are composed of metal, rubber, or plastic, but sometimes they can be composed of hard steel, especially if their utilization is done in sensitive and high-quality joints. Washers have a hole in their centre, and they are employed together with threaded fasteners.

If any fastener is driven into any object or machinery that does vibration, it might loosen to a point where it gets moved out. Spring washers ensure that this does not happen. They give an axial load to ensure that fastener is secured in an object. Some of the various kinds of spring washers are conical or Belleville, dome spring, wave spring, finger spring, and crescent spring. In general, manufacturers use spring washers to prevent components from damage done by temperature and corrosion. Manufacturers use them in railways, nuclear, oil, marine, shipbuilding, mechanical, and automobile industries.
