Hex Head Bolts Galvanized

Grade 2 (A307A) Hex Bolts are fasteners made from low carbon steel that achieve their strength primarily from cold working during the cold forming manufacturing operation.

Hot-dip galvanized steel had been effectively used for more than 150 years. The value of hot-dip galvanizing stems from the relative corrosion resistance of zinc, which under most service conditions is considerably better than iron and steel. In addition to forming a physical barrier against corrosion, zinc, applied as a hot-dip galvanized coating protects exposed steel. Furthermore, galvanizing for protection of iron and steel is favored because of its low cost, the ease of application, and the extended maintenance-free service that it provides.

Hot-dip galvanized threaded bolts require tapping oversize hex nuts for mating.
