Hex Head & Carriage Bolts

Hex Head Bolts

Bolts have a big advantage over screws in many applications: joints don’t depend upon threads cut into the wood for their strength. Exterior projects like decks and docks often use lots of bolts but require fasteners with significant corrosion resistance – often tough to find. These heavy-duty hex-head cap screws are made of corrosion-resistant 18-8 stainless steel or hot-dip galvanized steel, for use on demanding exterior projects. Use “Anti-Seize” on larger sizes to prevent galling.

Carriage Bolts

Carriage bolts have a nice, smooth, snag free head that is perfect for outdoor projects, deck furniture and even the deck itself. We offer top-quality carriage bolts in both 18-8 stainless steel and in hot dip galvanized. Use stainless steel carriage bolts in seaside applications or where corrosion resistance is important; use hot-dip galvanized carriage bolts for freshwater docks, inland decks and other outdoor structures. Torque washers are recommended for use with softwoods like pressure-treated lumber.
