Hillman Carriage Bolts and Nuts 5/16-18 inch x

Hillman zinc plated, steel, carriage bolts are designed to fasten a wooden face to either a wood or metal frame. The smooth, domed head offers a semi-flush, low-profile finish to applications where spacing is tight. The zinc plating is rust resistant and provides a beautiful, consistent finish while the steel material offers durability. The square shoulder locks into material, eliminating the need for a flat washer. For installation, drill a hole in the material that matches the diameter of the bolt.
