Everbilt 3/4 in.-10 x 8 in. Galvanized Carriage Bolt (10-Pack)

Carriage bolts have a smooth rounded head with a square neck underneath that locks into wood when tightened. Use with a pre-drilled hole and secure with a hex nut and washer to prevent spinning. They are great fasteners for decks, play equipment, docks, fencing, and furniture.
