Leading Manufacturer for 12.9 Hex Bolt - Carriage Bolt – Changlan

Product Description

1. 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.

2. Carriage bolts are generally used for marble installation of dry hangers. When tightening, the bolt rod will not rotate because of the square neck, so it is easy to fix and install. It is mainly used in some places where countersunk head screws are needed.

Specification

High strength wagon bolt increases the toughness of the bolt and can better withstand non-stop rotation. The quality of parts and components directly determines the quality of the products produced. This is the difference between the products produced by a large machine and those produced by a small workshop. CarRIAGE bolts of standard parts have a large market. But in addition to standard carriage bolts, there are also non-standard carriage bolts

In short, no matter what type of high-strength wagon bolts, they all play the role of “small screw, big purpose”. This high-strength wagon bolt is the fighter of bolts. Different specifications lead to their different roles, so we should choose the carriage bolts needed by our machinery, and better production is the right way.
