The Forgefix Coach Bolt & Nut (M12 x 240, 5 Pack) offers a reliable and versatile fastening solution specifically designed for low load-bearing timber-to-timber applications. Featuring a unique square neck to prevent twisting, these zinc-plated bolts are ideal for DIY outdoor and indoor projects, though users should ensure they are not used in high-stress structural situations where heavier loads are expected.
Versatile Fixing: Suitable for a wide array of timber joining tasks, enhancing project flexibility.
Square Neck Design: Engineered to embed firmly into timber, preventing the bolt from rotating during tightening and ensuring a secure fix.
Zinc-Plated Finish: Provides enhanced corrosion resistance, making the bolts suitable for both indoor and outdoor use in various weather conditions.
M12 x 240 mm Dimensions: Features a substantial M12 thread diameter and a 240mm length, ideal for joining thicker timber sections.
Timber-Specific Application: Optimized for creating strong, stable connections in timber, from garden furniture to fence panels.
Complete Pack: Each pack includes five M12 x 240mm coach bolts along with their corresponding hex nuts, ready for immediate use.
Anti-Twist Stability: The square neck design ensures the bolt stays firmly in place once embedded, simplifying installation.
Corrosion Resistance: Zinc plating offers good protection against rust and wear, extending the life of your fixings.
Strong Timber Fastening: Provides secure and durable connections for timber structures.
Ease of Use: Comes as a complete set of bolt and nut, requiring minimal additional components.
Low Load Bearing: Not suitable for high-stress or critical structural applications where heavy loads are anticipated.
Specific Size: The M12 x 240mm size may not be appropriate for all projects, requiring specific pre-drilling.
Timber Only: Primarily designed for timber, and less effective in other materials without additional components.

The Forgefix Coach Bolt & Nut excels in applications where a strong, stable, and twist-resistant timber-to-timber connection is needed for low load scenarios. Its square neck design is a standout feature, digging into the timber as the nut is tightened, which completely prevents the bolt from spinning. This makes for a much easier and more secure installation compared to standard bolts.
Common Use Cases:
Garden Furniture Assembly: Ideal for benches, tables, and other outdoor wooden furniture where durability and weather resistance are key.
Pergola Construction: Provides reliable fixings for the timber framework of garden pergolas, ensuring stability.
Fence Panel Fixing: Securely attaches fence panels to posts, resisting movement and weathering.
Decking Frames: Useful for joining timber sections in decking sub-structures, provided load-bearing is considered.
Thanks to its zinc-plated finish, these bolts offer good protection against the elements, making them a practical choice for outdoor projects. For optimal performance, always ensure you pre-drill holes of the correct diameter (slightly smaller than the bolt's thread, but wide enough for the shaft, and allow for the square neck) to allow the square neck to bite properly and prevent timber splitting.
Preparation: Identify the timber sections you wish to join. Mark the drilling points accurately.
Pre-Drill: Using a suitable wood drill bit, pre-drill a pilot hole through both timber sections. The drill bit diameter should be slightly smaller than the bolt's shank diameter (M12 in this case) but large enough to allow the bolt to pass through without excessive force. Ensure the depth accommodates the full length of the bolt.
Insert Bolt: Push the coach bolt through the pre-drilled holes. The head of the bolt should sit flush against the timber surface.
Embed Square Neck: Gently tap the head of the bolt with a mallet or hammer to embed the square neck into the timber. This action prevents the bolt from rotating during tightening.
Attach & Tighten Nut: Place the hex nut onto the threaded end of the bolt. Use a spanner or wrench to tighten the nut firmly until the connection is secure. Do not overtighten, as this can crush the timber.
Timber: Primarily designed for joining timber to timber. Suitable for various wood types, including softwoods and hardwoods.
Hole Size: Requires a pre-drilled hole that matches the bolt's M12 diameter (12mm) for the shaft, with careful consideration for embedding the square neck.
Load Bearing: Best suited for low load-bearing applications. Not recommended for primary structural components under heavy stress.
Corrosion Protection: The zinc-plated finish provides good resistance to rust. Avoid damaging this coating during installation.
Inspection: Periodically check fasteners in outdoor applications for any signs of loosening or corrosion, especially after extreme weather conditions. Tighten if necessary.
Cleaning: If exposed to dirt or debris, a simple wipe-down with a damp cloth can maintain their appearance.
