About Steel Heavy Hex Nut, Hot-Dipped Galvanized
The grade DH steel heavy hex nut has a hot-dipped galvanized finish and meets American Society of Mechanical Engineers ASME B18.2.2 and American Society for Testing and Materials ASTM A325 specifications. The heavy hex nut is taller and wider than a standard hex nut for a stronger hold and better security. It has six flat sides that a wrench can grip to turn from the side, enabling use when there is no space above the nut. Grade DH steel, composed of carbon steel, is often used in applications where strength is the primary consideration and is harder than Grade C steel. The hot-dipped galvanized finish offers excellent corrosion resistance.Nuts are internally threaded fasteners that are used with bolts and threaded rods and studs to connect components. Several different nut styles fit a variety of application and installation requirements. Some styles, such as hex nuts, acorn nuts, flange nuts, and coupling nuts, must be tightened with a tool. Others, such as eye nuts, thumb nuts, and wing nuts, can be tightened by hand. Some nuts have a self-locking mechanism, such as a nylon patch or distorted threads, that makes them suitable for applications with a high amount of vibration.
