HILLMAN 1/4 in. X 2-1/4 in. L Zinc-Plated Steel Carriage Bolt 100 pk

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 but may not work for all exterior projects.
