Conquest 1/2" x 3-1/2" Carriage Bolt - 18-8 Stainless Steel

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.

Built for professionals and dedicated DIYers, the Conquest 1/2" Carriage Bolt offers outstanding strength and corrosion resistance for structural fastening. Crafted from premium 18-8 stainless steel, it withstands harsh outdoor and marine environments, making it ideal for decks, pergolas, fencing, and more.

This bolt features a round head and square neck that locks into wood or metal to prevent rotation during tightening. Whether you’re working on timber-to-metal or timber-to-timber projects, this bolt delivers smooth finishes and reliable performance across a range of construction and fabrication applications.

Key Features

  • Material: 18-8 Stainless Steel for high corrosion resistance in outdoor and marine environments
  • Thread Type: Coarse, 13 threads per inch (TPI)
  • Head Type: Round Head with Square Neck to prevent spinning during installation
  • Versatile Sizing: Available in multiple diameters and lengths for various clamping and pull-through applications
  • Aesthetic & Functional: Clean, polished look ideal for exposed applications

Applications

  • Deck construction and timber framing
  • Fencing, pergolas, and outdoor structures
  • Marine hardware and coastal construction
  • Roof framing and high-moisture environments
  • General construction, renovation, or repair

Installation Tips

  • Drill a clearance hole through outer material to allow the square neck to lock in place
  • Use with 18-8 stainless steel hex nuts and washers for full corrosion resistance
  • Check tightness after initial loading for optimal holding strength
