The zinc plating offers corrosion resistance and has a reflective appearance. The square neck prevents the bolt from turning once installed, even when a nut is tightened. The round head has a domed shape.Carriage bolts, also called round head square neck bolts, are square-necked threaded fasteners commonly used in wood fastening applications. The bolt’s square neck prevents it from turning once installed using a nut.
