Carriage bolts, also known as carriage screws or coach bolts, are a type of fastener featuring a round head and square neck. The smooth, dome-shaped head protrudes from the attached surface while the square neck prevents the bolt from turning as it's tightened. The threaded portion of the bolt is located beneath the neck and is inserted into a pre-drilled hole. Carriage bolts are commonly used in building and construction projects to secure heavy timber and lumber. Coach bolts are also used in decorative applications where the protruding head adds a unique visual element to the design.
