What are Carriage Bolts?  

Carriage bolts, also known as coach bolts, are round-headed bolts with a square neck directly below the head. This square neck helps to prevent the bolt from turning when tightened, making it ideal for use in wood or metal connections. Carriage bolts are often paired with nuts and washers to create a secure fastening solution.
