Washers, typically made from plastic or metal, are thin plates with a hole in the center. They are used for various purposes, including:

  • Distributing the load of a threaded fastener (nut, screw, or bolt) to prevent damage to the material being fastened.
  • Preventing galvanic corrosion by acting as a buffer between dissimilar metals.
  • Providing stability and preventing loosening due to vibration in certain applications.
  • Available in a wide variety of materials to match specific application needs, including corrosion-resistant and high-durability options.
