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.
