Carriage Bolts – 12″
Fasten metal to wood, metal to metal, and other heavy-duty materials with our 12″ zinc-plated steel carriage bolts. These bolts are a reliable fastening solution for decks, docks, fencing, gates, play equipment, property repairs, maintenance work, REO jobs, and general construction applications.
Each carriage bolt features a smooth, rounded head for a clean finished look and a square neck designed to help lock the bolt into place when tightened. For proper installation, the bolt should be inserted through a pre-drilled hole and secured with the included hex nut and washer to help prevent spinning.
Made from zinc-plated steel, these 12″ carriage bolts offer strength, durability, and added resistance against rust and weather exposure, making them a practical choice for indoor and outdoor projects.
