Carriage bolt class 4.8 Round Head Square Neck Bolts

Short Description:

Carriage bolts are divided into large semi-round head carriage bolts (corresponding to standard GB/T14 and DIN603) and small semi-round head carriage bolts (corresponding to standard GB/T12-85) according to the head size.
The carriage bolt is applied in the slot, the square neck is stuck in the slot during the installation process, which can prevent the bolt from rotating, and the carriage bolt can move parallel in the slot. Because the head of the carriage bolt is round, there is no design of available assisting tools such as a cross slot or hex, and it can also play a role in preventing theft during the actual connection process.
Our factory can customize and produce carriage bolts of different specifications and materials for you, welcome your inquiry.
