Generally speaking, bolts are used to connect two objects, usually through light holes, and need to be used in conjunction with a nut. Tools usually use a wrench. The head is mostly hexagonal, generally large. The carriage bolt is applied in the groove. The square neck is stuck in the groove during the installation process, which can prevent the bolt from rotating. The carriage bolt can move parallel in the groove. Because the head of the carriage bolt is round, there is no cross slot or hexagon and other available booster tool design, in the actual connection process can also play the role of anti-theft.
