1/4 F436 Round Structural Washers

F436 Hardened Round Structural Washers, sometimes just called Structural Washers are specified under ASTM F436. These washers are through hardened or carburized to add strength, but are physically smaller than a standard F844 flat washer. Generally the washers comply with the SAE pattern. Available sizes 1/4" through 4".
