5/8" Hot Dipped Galvanized Carriage Bolt, Grade 2 UNC

Hot dipped galvanized Grade 2 carriage bolts in 5/8" diameter, available in a range of lengths. A smooth domed head sits above a square neck that pulls into the wood as the nut is tightened, locking the bolt in place so it cannot spin. Ideal for wood-to-wood and metal-to-wood connections.

The hot dipped galvanized coating offers far better corrosion resistance than standard zinc-plated steel, making these bolts a solid choice for decks, fences, pressure-treated lumber and other outdoor wood structures.

Tip: always place a flat washer between the wood and the hex nut to prevent the nut from pulling into the wood.
