Conquest 3/8" x 3-1/2" A307 Carriage Bolt with Galvanized Finish

When pairing a nut with a hex bolt, the material and finish must match. If these do not match, the nut will not fit the bolt.

The Conquest 3/8" A307 Carriage Bolt is crafted for general-purpose outdoor use, combining strength, durability, and corrosion resistance. Its hot dip galvanized finish offers superior protection in wet or treated lumber environments, making it ideal for structural wood connections in decks, fences, and timber framing.

This bolt features a domed round head for a clean appearance and a square neck that grips into wood or metal to prevent spinning during installation. Manufactured from low-carbon steel and compliant with ASTM A307 standards, it offers reliable tensile strength for residential, agricultural, or light commercial construction.

  • Thread Type: Coarse
  • Threads Per Inch (TPI): 16
