Carriage bolts are designed for through-bolting where the bolt's square neck is used to keep the bolt from turning as a nut is tightened on the other end. Using a carriage bolt will really clean up the appearance of your outdoor projects-like deck furniture, decks and docks. Available in marine grade Hot-Dipped Galvanized for corrosion resistance.
Carriage bolts were originally designed to attach the wheels to the axles of carriages during the 17th and 18th centuries. The best way to install a carriage bolt is to insert it into the pre-drilled hole and tap the bolt so the head is flush with the surface. Fasten with a flat washer, a lock washer, and a nut. The lock washer stops the bolt from loosening, but you can also add an additional nut and tighten the two nuts together.

Verified Purchase
It was not clear to me when I purchased them, but the galvanized carriage bolts I purchased came with nuts. I had ordered a box of nuts as well but turns out I did not need them.
