The Forgefix M12 x 130 Coach Bolts and Nuts are essential fixings designed for joining timber in low load-bearing applications, making them ideal for garden furniture, pergolas, and fence panels. These zinc-plated bolts feature a square neck to prevent twisting, ensuring strong and reliable fastenings that can withstand the elements. However, it is crucial to remember their limitation to low load-bearing uses for optimal performance and safety.
Versatile Fixing: Suitable for a wide range of timber-to-timber construction projects.
Anti-Twist Square Neck: Engineered with a square neck that bites into timber, preventing the bolt from spinning during tightening.
Zinc-Plated Finish: Provides enhanced corrosion resistance, making them suitable for outdoor applications and exposure to elements.
Optimal Dimensions: Features an M12 thread and a length of 130 mm, ideal for various timber thicknesses.
Complete Set: Each bolt comes supplied with a corresponding hex nut, ensuring immediate usability.
Low Load-Bearing Design: Specifically designed for applications where high load capacity is not required, preventing material stress.
Durability: Crafted to provide strong and lasting fastenings for your projects.
Prevents Spinning: The square neck design effectively stops the bolt from turning when tightening the nut.
Weather Resistant: Zinc-plated finish offers good protection against rust and corrosion, suitable for outdoor use.
Easy to Use: Supplied with hex nuts, simplifying installation and ensuring a secure fit.
Multi-Purpose: Excellent for various DIY and construction tasks involving timber, from furniture to fencing.
Low Load Applications Only: Not suitable for high-stress or structural applications where significant load bearing is required.
Specific Size: M12 x 130mm might not be universally applicable for all project needs, requiring correct pre-drilling.

The Forgefix Coach Bolt and Nut provides dependable fastening for timber-to-timber connections, excelling in scenarios where the primary need is to join wooden components without supporting heavy dynamic or static loads. Their M12 x 130mm size makes them particularly useful for common timber dimensions in outdoor and indoor projects.
Common Applications:
Garden Furniture Assembly: Ideal for securing legs, backrests, and crossbeams on wooden benches, tables, and chairs.
Pergola Construction: Useful for joining timber rafters and posts where the structure's overall stability is shared among multiple connections and not solely reliant on one bolt.
Fence Panel Fixing: Securely attaches fence panels to posts, resisting elements and ensuring stability.
Timber Joist Construction (Low Load): Can be used in light-duty timber framing or non-structural joist work where the primary function is alignment and basic connection.
When installed correctly, the square neck of the coach bolt bites into the timber, preventing the bolt from rotating as the hex nut is tightened. This design allows for a single-tool tightening approach (using a spanner or wrench on the nut), as the bolt head can be left proud or hammered flush into the timber, depending on the application and aesthetic preference. The zinc-plating ensures that these fastenings remain robust against moisture and environmental exposure, offering lasting performance in outdoor settings.
Drill Pilot Hole: Using a wood drill bit, create a pilot hole through both pieces of timber to be joined. The drill bit diameter should match the bolt's shaft diameter (M12 in this case, so 12mm).
Insert Bolt: Push the coach bolt through the drilled hole. Ensure the square neck section beneath the bolt head fully seats into the timber. You may need to gently tap the bolt head with a hammer to ensure the square neck embeds firmly, preventing rotation.
Attach Nut: Place the provided hex nut onto the threaded end of the bolt.
Tighten: Using a suitable spanner or wrench, tighten the hex nut until the connection is secure. Do not overtighten, as this can crush the timber.
Material: Primarily designed for joining timber to timber.
Load Bearing: Suitable only for low load-bearing applications. Do not use for structural elements that bear significant weight or stress.
Hole Size: Requires a 12mm diameter hole for the M12 bolt.
Storage: Store unused bolts and nuts in a dry environment to prolong their lifespan and prevent premature corrosion.
Application Suitability: While zinc-plated, for extreme outdoor conditions or marine environments, consider additional rust-preventative coatings or alternative materials if long-term exposure is critical.
Inspection: Periodically inspect installed bolts in outdoor applications for signs of wear or loosening, and re-tighten if necessary.
