Prime-Line 9063305 Carriage Bolts, 5/16 In.-18 X 6 In, A307 Grade A Hot Dip Galvanized (15 Pack), Zinc

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.
