A carriage bolt is a heavy-duty industrial fastener characterized by its smooth, round head and a distinct square neck located immediately beneath the head. This unique square neck is designed to grip securely into the part being fixed, effectively preventing the bolt from turning when the nut is tightened. This self-locking feature makes installation highly efficient and secure, as the square base anchors the bolt in place.
Because of their smooth finish and tamper-resistant design, carriage bolts are highly versatile fasteners used securely across a variety of building projects. They are ideal for applications where the square neck can sink into the mating surface to lock the fastener in place. Common applications include:
