Product Description

Product Description

Carriage Bolt, also known as a square neck bolt, features a round or oval head and a square-shaped neck. The square neck is designed to embed into the connected parts when tightened, preventing the bolt from rotating. Commonly used in connection scenarios such as wooden structures and metal frames, it needs to be used with a nut. Made of carbon steel or stainless steel, its surface can be galvanized for rust prevention. Specifications are divided by diameter and length. It is easy to install and provides stable connection, serving as a common fastener in the industrial and construction fields.
