Description

ASME B18.2.1 black finish ASTM A325 structural heavy hex bolt

Heavy Hex Bolts are designed for use in a variety of high temperature, high strength industrial applications, such as with steel fabrication and general construction. They feature a thicker head than standard or regular hex bolts, and offer a greater bearing surface that distributes the clamping load over a wider area. Heavy hex bolts can be made with a few different materials including low and medium carbon steel, alloy, and stainless steel, and are available plain, hot dipped galvanized, phosphate, zinc or cadmium plated. Some sizes of heavy hex bolts are fully threaded while other sizes offer a smooth shoulder area.
