Hex Bolt Galvanized, A-449. ASTM A-449 is a medium strength bolt manufactured from a medium carbon or alloy steel that develops its mechanical values through a heat treating process. It is intended for general engineering applications. ASTM A-449 is virtually identical in chemistry and strength to ASTM A-325 however, A-449 is more flexible because it covers a larger diameter range.
