Carriage bolts are threaded fasteners with round heads that are used to hold wood and metal together. Carriage heads are large smooth and domed with no drive.
For usage- carriage bolt is pushed into a hole the same size as the shank and then hammered in the rest of the way, where the square shoulder locks it firmly in place. Used whenever a smooth finish surface is needed so that nothing becomes snagged on the fastener. Zinc plating, retards the corrosion rate in a normal atmosphere.
