what is Carriage Bolts?

Carriage Bolts are a special type of bolt.

Construction features: Carriage Bolts have a dome or countersunk head, and below the head, there is a short quadrilateral section on the screw. This quadrilateral section is designed to ensure that the bolt does not rotate when the nut is tightened, thus providing a stable fixing effect.

Application areas: Due to its unique construction, Carriage Bolts are widely used in the vehicle and machine tool industries, especially in situations where a stable connection is required and it is not easy to loosen.

Fixing effect: The quadrilateral section can be firmly embedded in the fixed part (usually wood), thereby preventing the bolt from rotating when the nut is tightened. In addition, some types of Carriage Bolts have longitudinal ribs on the quadrilateral section, which can better embed into the metal parts and provide a stronger fixing effect.

Summary: Carriage Bolts play an important role in many fields with its unique construction and excellent fixing effect.
