Carriage Bolts (Coach Bolts)

Carriage Bolt Advantages

Carriage bolts are easy to use, durable and can be used across a range of applications. Carriage bolts are designed with a flat surface to form a secure connection with wood and other materials, and they can only be removed from the nut side of the bolt for added security. The smooth domed head lowers the cause of snagging other materials or causing damage to surrounding materials. The domed head also adds aesthetic appeal. Carriage bolts are self-locking, and the square segment of the shank will stop the bolt from turning when it is installed.
