What does the carriage bolt look like?

  What does the carriage bolt look like? The bolts of the carriage bolts do not rotate because of the square neck, which is convenient for fixing and installation. It is mainly used in some places where countersunk screws are required. The materials used are generally grades 2 and 5 of steel and stainless steel, which is also a common type of carriage bolts.

The carriage bolt consists of a head and a screw. It needs to be used with a nut to fasten and connect two parts with through holes. The screw is a cylinder with external threads. According to the size of the head, it can be divided into large semi-circular carriage bolts and small semi-circular carriage bolts. The standard for large semi-circular carriage bolts is GB/T14 and DIN693. The standard for small semi-circular carriage bolts is GB/T12-85, GB801. For the low square neck, the user can select different types according to the actual use when selecting.

The carriage bolt also has a big advantage. Because the head of the carriage bolt is round, there is no design of the available power tools such as a cross recess or a hexagon socket, and it can also function as an anti-theft during the actual connection process.
