Galvanized steel carriage bolts are heavy-duty fasteners featuring a smooth, rounded head and a square neck designed to lock into wood or metal. This specialized neck prevents the bolt from turning during installation, allowing for secure tightening from a single side with a nut. The hot-dipped galvanized coating provides a thick, rugged layer of protection that is significantly more resistant to rust and weathering than standard plating. This makes them the premier choice for outdoor structural projects like decks, fences, and playground equipment. These bolts combine a clean, snag-free finish with the extreme durability needed to withstand harsh environmental conditions.
