F436 Bevel Washer, Galvanized

Manufacturers:

ASTM F436 thru hardened bevel washers are square or rectangular washers with a beveled 1 to 6 ratio surface. For use with American standard beams and channels to compensate for lack of parallelism. F436 bevel washers are designed for structural applications and are commonly used with ASTM F3125 Grade A325 and Grade A490 fasteners. Dimensional, chemical, and mechanical specifications are governed by ASTM F436. Available in hot dip galvanized finish, which provides a corrosion resistant zinc coating.
