Â
Generally speaking, the Bolt is used to connect two objects, usually through the smooth hole, which needs to be used together with the nut, and a single bolt does not work. The tools are usually spanners. The head is mostly hexagonal, generally larger. The carriage bolt is used 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 in parallel in the groove. Because the head of the carriage bolt is round, there is no cross groove or inner hexagon, which can be used to assist the design of tools. In the actual connection process, it can also play the role of anti-theft.
