Carriage Bolts

A carriage bolt is a round-headed bolt with a square neck, commonly used in woodworking, construction, and outdoor projects. Its smooth, rounded head prevents damage to materials, making it ideal for use in wooden structures, fences, bridges, and outdoor furniture. The square neck locks into the material, preventing the bolt from spinning during installation. Carriage bolts are typically made of galvanized or stainless steel, providing enhanced corrosion resistance.
