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.
