5/8-11 Hot Dip Galvanized Steel Carriage Bolt. Diameter - Thread Pitch: 5/8 - 11.
5/8-11 Carriage bolts have a domed or countersunk head, and the shank is topped by a short square section under the head. The Square section grips into the part being fixed (typically wood). It prevents the bolt from turning when the nut is tightened.Hot Dipped Galvanized assemblies should be used exclusively. If you use a HDG bolt you must also use a HDG nut. To "go green" and reduce our use of plastic all product quantities will be packaged in as few packages as possible.
