Description

Conquest Carriage Bolts made from 18-8 stainless steel are the go-to fastener for builders and DIYers alike who need strength, corrosion resistance, and clean aesthetics. Whether you're assembling outdoor furniture, framing a deck, or working on fencing and marine projects, these bolts deliver a secure fit that won’t rust out or come loose.

The round, domed head and square neck under the head lock neatly into wood or metal surfaces, helping prevent spin during installation. They’re ideal for applications where the fastener needs to sit flush on one side for safety or appearance, no snagging, no sharp edges, just solid performance.

These bolts come in a range of diameters and lengths, giving you options to suit different materials and project specs. Pair with a washer and hex nut for a snug, professional-grade hold.

Key Features

  • 18-8 Stainless Steel: Offers dependable corrosion resistance, ideal for outdoor, coastal, or high-moisture environments.
  • Rounded Head Design: Clean, snag-free appearance perfect for visible joints and touchable surfaces.
  • Square Neck Grip: Locks into place to prevent turning as you tighten from the other side.
  • Multiple Sizes Available: Choose the right fit for light-duty to heavy-structure applications.
  • Rust-Free Finish: Stays looking good for the long haul—rain or shine.

Common Applications

  • Deck framing and outdoor furniture
  • Fencing and gates
  • Dock and marine construction
  • Pergolas and timber framing
  • General wood-to-wood or wood-to-metal fastening

Installation Tips

  1. Drill a pilot hole matching the bolt diameter.
  2. Tap the bolt into place to seat the square neck into the material.
  3. Secure with a washer and hex nut on the opposite side.
  4. Tighten using a wrench while keeping the domed head flush against the surface.
