Hot Dipped Galvanized Carriage Bolts
Domed Head Bolts - Hot Dip Galvanized Steel
A carriage bolt, also known as a coach bolt, has a domed or countersunk head. The shank is topped by a short square section under the head of the bolt. The square section grips into the part being fixed (typically wood), preventing the bolt from turning when the nut is tightened.
A hot dipped galvanized finish consists of running a steel fastener through a molten zinc bath that creates a tightly bonded alloy finish. This finish creates a highly corrosion resistant finish in the fasteners.
