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: 5/16 inch-18 X 4-1/2 inch
  • Features a smooth rounded head as opposed to a standard hex head
  • Square shoulder allows for nut to be tightened or loosened
  • Often used in cases where a protruding bolt head could cause injury
  • Nuts and washers not included, ensure washers and nuts are same diameter
