Hexagon bolt is our company's main products, mechanical parts, cylindrical threaded fasteners with nuts. It is a kind of fastener composed of head and screw. It is used for fastening and connecting two parts with through holes. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
Generally speaking, a bolt is used to connect two objects, usually through a light hole. It needs to be used with a nut. Tools usually use a wrench. The head is mostly hexagonal and generally larger. Carriage bolts are applied in the groove. The square neck is stuck in the groove during installation and can be lifted to prevent the bolt from rotating. Carriage bolts can be moved in parallel in the groove. Because the head of the carriage bolt is round, there is no cross groove or hexagonal available power tools such as the design, in the actual connection process can also play the role of anti-theft.
