Carriage bolts are divided into large semicircular head carriage bolts (corresponding to standard GB / T14 and DIN693) and small semicircular head carriage bolts (corresponding to standard GB / T12-85) according to head size. Carriage bolts, a type of fastener consisting of a head and a screw (cylinder with external thread), need to be matched with nuts to fasten and connect two parts with through holes.
