Specification Brand : RAW PRODUCTS CORP BulletPoint1 : Hot dipped galvanized carriage bolts have a domed or countersunk head, and the shank is topped by a short square section under the head. BulletPoint2 : The square section grips into the part being fixed (typically wood), preventing the bolt from turning when the nut is tightened. BulletPoint3 : The square shank of the bolt allows it to lock into place when inserted into a round hole in wood or a square hole in a metal strap, the unthreaded square shank pulls into the wood creating a tight connection. BulletPoint4 : Carriage Bolts under 6 inches are fully threaded. Sizes over 6 inches in length have a shoulder. BulletPoint5 : Hot Dipped Galvanized assemblies should be used exclusively. If you use a HDG bolt you must also use a HDG nut.
