DESCRIPTION
Carriage bolts have a domed head, and the shank is topped by a short square section under the head of the bolt. The square section grips into the part being fixed, preventing the bolt from turning when the nut is tightened. Carriage bolts are often used to fasten wood panels or board to masonry or one another, as well as wood beams. The square shank of the bolt allows it to lock into place when inserted into a round hole in wood or a square hole in a metal strap, and the unthreaded square shank pulls into the wood, creating a tight connection. Shorter length carriage bolts are fully threaded(FT), while longer lengths may be partially threaded(PT). These will be designated in the listing having either FT or PT in the title.
