Description

Built for professionals and serious DIYers, this stainless steel carriage bolt delivers the durability and performance needed for demanding jobs. With a round head and square neck design, it provides smooth finishes and firm locking into wood or metal, preventing spin during tightening. Manufactured from corrosion-resistant 18-8 stainless steel, these bolts are ideal for indoor, outdoor, and marine applications. Offered in multiple lengths and diameters, they’re compatible with a wide range of construction and fabrication needs. These coach bolts pair with compatible 18-8 stainless steel hex nuts and 18-8 stainless steel washers.

Key Features

  • Made from 18-8 stainless steel for excellent corrosion resistance in high-moisture or outdoor environments.
  • Round head and square neck design prevents bolt rotation once installed.
  • Available in a wide range of diameters and lengths to accommodate various material thicknesses and project needs.
  • Fully or partially threaded depending on size, ideal for both clamping and pull-through applications.
  • Clean, finished appearance for exposed applications like decks, pergolas, and framing.

Applications

  • Timber-to-metal or timber-to-timber connections in decking, fencing, pergolas, and framing.
  • Exterior or marine environments where rust resistance is essential.
  • Roof framing and structural fastening where aesthetics and hold strength matter.
  • Any general construction, renovation, or repair project where strength, corrosion resistance, and reliability are a must.

Installation

  1. Choose the correct diameter and length to ensure full thread engagement and proper grip.
  2. Drill a clearance hole through the outer material, then insert the bolt so the square neck bites into the wood or metal and prevents turning.
  3. Secure with a compatible 18-8 stainless steel nut and washer for best performance.
  4. For outdoor or corrosive environments, use stainless hardware throughout to maintain corrosion protection.
  5. Re-check tightness after initial use/load for maximum holding power.
