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.
A bolt is a screw with a larger diameter or without a head, such as a stud. Generally, it is not called "stud" but "stud". The most common form of a double-ended stud is threaded at both ends with a smooth rod in the middle. Most typical use: anchor bolt, or similar anchor bolt, thick connection, when ordinary bolt cannot be achieved。
Hexagon bolts are metal fittings also known as outer hexagon screws, outer hexagon screws or outer hexagon bolts. In general, high strength bolts are used to connect the main components of building structures.
