Galvanized F436 Structural Flat Washers

Galvanized F436 structural washers are through-hardened steel washers made to ASTM F436, with a hot dip galvanized finish. They are specified with galvanized A325 structural bolts and 2H heavy hex nuts in outdoor steel connections, so bolt tension doesn't relax into the steel. We stock 1/2", 5/8", 3/4" and 1".
