A563 Grade DH UN8 class 2B zinc plating structural Heavy hex Nut

The ASTM A563 specification covers carbon and alloy steel nuts for general structural and mechanical uses on bolts, studs, and other externally threaded parts. A563 nuts have a wider variety of uses compared to the A194 nuts. Because of this, it’s important for the customer to specify which variation of A563 nuts they need, including grade, style, nominal size, thread series, coating, and other special requirements. We produce A563 nuts in Grades A, C, DH, and DH3. DH nuts are made of medium carbon steel and heat treated. They are recommended for F3125 A490 structural bolts and in many other applications. DH3 nuts are corrosion resistant and have certain weathering characteristics.
