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.
