Build it Once. Build it Right. Use Hardware That Lasts.
For projects exposed to the harsh reality of the outdoors, standard hardware just doesn't cut it. At Vintage Parts Revival, we offer New Old Stock (NOS) fasteners that were made for the toughest conditions. This 1/2" x 3" carriage bolt isn't just plated; it's protected by a true Hot-Dip Galvanized (HDG) finish, making it the ultimate choice for projects that have to endure.
From Mississippi river docks in Davenport to farm gates that face all four punishing seasons, this is the hardware you can trust. Unlike a thin zinc plating, hot-dipping creates a thick, resilient layer of zinc that is metallurgically fused to the steel, providing decades of superior protection against rust and corrosion. The classic carriage bolt design provides a smooth, safe head on one side, while the square neck locks firmly into wood, preventing the bolt from spinning while you tighten the nut.
Don't rebuild it in five years. Use this genuine, heavy-duty NOS hardware and get the peace of mind that comes from doing the job right the first time.
