Everbilt 3/8 in. - 16 tpi x 3-1/2 in. Galvanized Coarse Thread Carriage Bolt (25-Piece per Box)

This carriage bolt features a smooth, rounded head with no external drive for a simple look. It boasts a square shank under the head that pulls into the material as nuts are tightened and prevents the bolt from turning once completely installed. Ideal for use in deck building, fence construction and outdoor furniture, a durable steel material provides longevity. For application, push bolt into a pre-drilled hole and then tighten in place with hex nuts and flat or lock washers.
