May 18, 2021 · 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. Gibraltar - 3/8" Screw, Alloy Steel Structural Flat Washer Structural washers are thick, strong washers used in heavy-duty building construction. For outside building applications, structural washers are typically coated or galvanized for corrosion
SAE washers generally have a smaller ID and OD than USS washers. Zinc-plated, zinc yellow-chromate plated, and chrome-plated steel washers are corrosion resistant in wet environments. Black ultra-corrosion-resistant coated and zinc-aluminum coated steel washers resist chemicals and withstand 1, 000 hours of salt spray.

Structural Bolts - ASTM A325 & ASTM A490 AALL ASTM A490 - Structrual Bolts, Alloy Steel, Heat Treated, 150-ksi Minimum Tensile Strength. Nuts and washers used in a structural joint with heavy hex structural bolts must also meet appropriate standards. Falling under ASME B18.2.6 dimensional standard, there are two chemical and mechanical designations for structural nuts; ASTM A563 and A194.
Structural washers F436; Material. Steel plain finish. A high strength carbon steel. Commonly used with structural bolts. Unplated finish. Hot dipped galvanized steel. A high strength carbon steel. Commonly used with structural bolts. Hot dipped galvanized is a coating for very good corrosion resistance. Washers - James GlenA hardened steel washer used in conjunction with structural bolts in heavy construction applications. The washer reduces galling between the tightened surfaces and spreads the load. The three external tabs identify it as a structural washer.ASTM F436 Flat Washers - Washers - Grainger Industrial SupplySteel Flat Washer, Hot Dip Galvanized Fastener Finish These hardened steel washers are designed for general-purpose and structural use with bolts, nuts, studs, and other threaded fasteners.
