A307B Heavy Hex Bolts

Grade B A307 heavy hex bolts are externally threaded fasteners made of carbon steel. These bolts are very similar to standard hex bolts however the head size across the flats and corners is larger providing a broader bearing surface. A307B bolts come in a black oxide finish or hot-dipped galvanized steel for corrosion resistance and are commonly used in piping systems and other high-pressure applications. Black oxide coatings are corrosion resistant in dry environments. Hot-dipped galvanized steel coatings are more corrosion resistant than zinc plating, giving these bolts a thicker coating than other finishes.
