Washers are a fastener component that is used in conjunction with a screw fastener such as a bolt and nut and that usually serves either to keep the screw from loosening or to distribute the load from the nut or bolt head over a larger area. Washers are also used for spacing, leveling, or sealing.

These sealing washers are used in combination with standard screws and bolts to seal out water, oil, dust, solvents and other materials or contaminants.

These washers are used in Radial or Axial load applications or with Bearings.
