Product Description Carriage Bolts are designed to fasten a wooden face to either a wood or metal frame. Its flat head is designed to eliminate the need for a washer and provide a semi-flush finish to applications. The square underside of the head is self locking to eliminate spinning and the need for a driving tool. The zinc plating is rust resistant and provides a beautiful, consistent finish; but, may not work for all exterior projects. From the Manufacturer Carriage Bolts have a smooth, rounded head that has a small square section underneath. They are used in wood connections utilizing the square neck under the round head which will sit into the hole to prevent the head from turning.
