Clipped hardened washers are used where space limitations require one side be clipped. These washers provide a smooth bearing surface and are used under the head of a bolt and / or a nut. The chemical, mechanical, and dimensional requirements for hardened washers are covered under the ASTM specification F436. Clipped hardened washers are through hardened or carburized to add strength, but are physically smaller than a standard F844 flat washer. See Portland Bolt’s technical information for suitable bolt or anchor bolt recommendations.
