DH Heavy Hex Nut, Galvanized US/CA

USA/Canadian ASTM A563 Grade DH heavy hex nuts are commonly used in structural bolting applications. DH nuts listed on this page are melted and manufactured in the USA or Canada. ASTM A563 covers standard specifications for carbon and alloy steel nuts. They are a common high strength nut used mainly in structural applications with F3125 Grades A325 and A490 bolting. In many applications, A194 Grade 2H nuts can be substituted for A563 Grade DH nuts. Dimensional specifications are governed by ASME B18.2.2. Heavy hex nuts provide increased bearing surface area over finished nuts. Available in hot dipped galvanized finish for corrosion resistance, dyed & waxed for added lubrication and accurate torquing.
