3/8" x 3" Black Carriage Bolt & Nut Lot of 25 screws heavy duty galvanized

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.

• Size: 3/8 in. x 3 in.
