Description

Carriage bolts feature a slightly rounded head and have no exposed sharp edges when fully fastened. Due to that reason, they are often used when a more aesthetic look is desired. They are commonly used on docks and on playground equipment or in cases where it may be difficult to reach the bolt head with a tool. The square shoulder on carriage bolts help to hold it in place while the nut is fastened.
