Carriage Bolts

What is a Carriage Bolt?

A Carriage Bolt is a bolt with a round or flat head and a shoulder that is either ribbed or square.

Carriage Bolt Uses

Carriage bolts are mostly used in wood to wood or wood to metal applications, where the shoulder can dig into the wood and keep the bolt from turning while the nut is being tightened.

Because of the round head, the carriage bolts are good for use in situations where a smooth surface is required for aesthetic, security, or safety purposes.
