The Forgefix Coach Bolt & Nut M12 x 200 is designed for users needing strong, weather-resistant fixings primarily for timber-to-timber connections, especially in outdoor settings. It excels at preventing twisting thanks to its square neck design, ensuring secure and stable assemblies. However, it is specifically intended for low load bearing applications, meaning it's not suitable for heavy structural work.
Versatile Fixings: Ideal for a range of timber construction projects.
Square Neck Design: Prevents the bolt from twisting within the timber when the nut is tightened, ensuring a secure fit.
Zinc Plated: Offers enhanced resistance to corrosion, making them suitable for outdoor exposure and helping them withstand the elements.
M12 Thread & 200mm Length: Standard sizing for robust timber fastening applications.
Low Load Bearing: Optimized for applications where excessive weight or stress is not a primary concern.
Complete with Hex Nuts: Each bolt comes with its corresponding hex nut for immediate use.
5-Pack: Convenient quantity for small to medium projects.
Anti-Twist Design: The square neck effectively prevents rotation during tightening, simplifying installation.
Weather Resistant: Zinc plating provides good protection against rust and corrosion for outdoor use.
Strong Fastening: Provides secure and durable joints for timber-to-timber applications.
Easy to Use: Simple to install with basic tools.
Low Load Bearing Only: Not suitable for high-stress or heavy structural applications.
Specific Application: Primarily designed for timber, not ideal for other materials without specific adaptations.

The Forgefix Coach Bolt & Nut M12 x 200 excels in applications where secure, non-twisting timber connections are required without heavy load requirements. Its primary strength lies in its square neck, which bites into the timber, preventing the bolt from spinning while the nut is tightened. This is particularly useful when working alone or in tight spaces where counter-holding the bolt head might be difficult.
Garden Furniture Assembly: Perfect for joining wooden components of outdoor benches, tables, or swings.
Pergola Construction: Suitable for fastening timber beams and uprights in garden pergolas.
Fence Panel Fixing: Provides a strong and weather-resistant method for attaching fence panels to posts.
Timber Joist Construction (Low Load): Can be used in non-structural timber joist work where the load is minimal, for example, decorative frameworks or light shelving units.
Always drill a pilot hole. The diameter of the pilot hole should be slightly smaller than the threaded part of the bolt, and a larger counterbore might be needed for the square neck to fully seat. The square neck must embed firmly into the timber to prevent spinning.
Ensure the square neck is fully engaged in the timber before tightening the nut to prevent stripping or damaging the timber surface.
For best results and to extend the life of your timber, consider using washers under the nut to distribute the load more evenly and prevent the nut from digging into the wood, especially in softer timbers.
Prepare the Timber: Mark the exact location for the bolt on both timber pieces you wish to join.
Drill Pilot Holes: Using an appropriate drill bit (e.g., a 12mm wood drill bit for the bolt body, or slightly smaller if working with very soft timber to ensure a snug fit for the thread, and a pilot for the square neck if needed), drill a clean hole through both pieces of timber. Ensure the hole is straight and perpendicular to the timber surface.
Insert the Bolt: Push the coach bolt through the drilled holes. Ensure the square neck of the bolt aligns with the timber and firmly seats itself into the wood. You may need to gently tap the bolt head with a hammer (using a block of wood as a buffer to protect the head) to ensure the square neck fully embeds.
Attach the Nut: Place the hex nut onto the threaded end of the bolt. For outdoor use or where aesthetic matters, consider adding a washer under the nut to prevent it from digging into the wood.
Tighten: Use a spanner or wrench (appropriate for M12 nuts) to tighten the hex nut until the connection is secure. Do not overtighten, as this can crush the timber or strip the threads.
Materials: Primarily designed for timber-to-timber connections. Can be used with other materials (e.g., thin metal brackets) if appropriate pilot holes are drilled and the square neck can still anchor securely into a timber surface.
Tools: Requires standard woodworking tools like a drill, drill bits (12mm), a hammer (optional, for seating the neck), and a spanner/wrench (M12 size).
Load: Compatible only with low load bearing applications. Do not use for structural elements that support significant weight or dynamic loads.
Zinc Plating: The zinc plating provides good corrosion resistance. However, in extremely harsh or consistently wet environments, some surface corrosion may eventually occur over many years.
Inspection: Periodically inspect outdoor installations for any signs of loosening or corrosion, especially after extreme weather conditions.
Cleaning: If needed, clean the bolts with a damp cloth. Avoid abrasive cleaners that could damage the zinc plating.
