Installation

Carriage bolts are designed for use in pre-drilled holes. Insert the bolt through the material so the square neck fits snugly into a square or pressure-fit round hole to prevent spinning. Secure with a compatible 1/4″-20 nut and washer (sold separately). Torque using a wrench or socket from the nut side, no need to grip the head.
