What use for?

Generally, bolts are used to connect two objects, usually through a light hole, and need to be used in conjunction with a nut, which alone does not connect. The tool is usually a wrench. The head is mostly hexagonal, etc., and is generally larger. Carriage bolts are used in grooves, and the square necks are stuck in the grooves during installation, which can prevent the bolts from rotating, and the carriage bolts can be moved parallel to the grooves. As the head of the carriage bolt is round, no cross slot or hexagonal and other available booster tool design, in the actual connection process can also play the role of anti-theft.

Through the above can be seen, carriage bolts and ordinary bolts is the difference between the head treatment, the head can not be loosened with tools, so the use of carriage bolts to fix two objects are divided into the inner and outer layers, the outer layer to stay in the head position of the carriage bolts, the internal with the nut to be fixed, the result is that, in the absence of access to the inner layer of the case, from the outer layer alone is basically impossible to loosen the carriage bolts, and thus up the safety of the role of reinforcing!
