A307 Hex Bolt, Galvanized

ASTM A307 Grade A hex bolts are common fasteners manufactured from low carbon steel. Dimensional specifications are governed by ASME B18.2.1. Grade marking consists of both the grade symbol "307A" and the manufacturer's identification mark. Inch series fasteners meeting ASTM A307 Grade A specifications are common/economical fasteners used for general applications. These bolts have a finished pattern head, whereas A307 Grade B bolts have a heavy pattern head. A307 hex bolts are available in hot dip galvanized finish, which provides a corrosion resistant zinc coating.
