GB / T14 - 85 Galvanized Carriage Bolts Of Steel For Fastening Connections

Product Description

Generally, the bolt is used to connect two objects, usually through a light hole, which needs to be used in conjunction with the nut (nut) and does not play a single connection. The tool usually uses a wrench. The head is more than six angles, generally large. The carriage bolts are applied to the grooves, and the tetragonal necks are stuck in the grooves during the installation process. The bolt can be prevented from turning, and the carriage bolts can move parallel in the slot. Because the head of the carriage bolt is round, and no cross slot or six angle can be used as a power assist tool, it can also play a role of anti-theft in the actual connection process.
