Prime-Line 3/8 in.-16 x 4 in. A307 Grade A Hot Dip Galvanized Steel Carriage Bolts (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.

• Flat head gives a smooth exterior finish
• Use to attach hardware to garage doors
• Steel construction offers long-lasting use and solid performance
