Hot Dipped Galvanized Carriage Bolts: Carriage bolts have a round smooth head with a square neck under the head. The square neck keeps the bolt from turning as a nut is tightened. These bolts are low carbon (Grade 2) steel. The Hot Dipped Galvanized coating is a thicker protective coating good for outdoor use, and recommended for use with treated lumber.
