Product Description

The carriage bolt has a large round head and a square neck below the head. It is also called a large semi-circular square neck bolt. It is generally used with a nut to fasten and connect two parts with through holes...

The carriage bolt is placed in the groove, and the square neck of the head is embedded in the groove of the connection member, which can prevent the bolt from rotating in the same direction during the installation process and can also move in parallel in the groove.
