Carriage Bolts, 1/4 in.-20 X 3-1/2 in., A307 Grade A Hot Dip Galvanized Steel (25 Pack)

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.
