The Forgefix M6 x 40 Coach Bolt & Nut kit is specifically designed for DIY enthusiasts and professionals working on low load-bearing timber construction projects, offering secure and versatile fastening with its innovative anti-twist square neck design. While highly effective for its intended purpose, it's crucial to note that these fixings are not engineered for high-stress or critical structural applications. This 10-pack provides durable, zinc-plated M6 x 40mm bolts and corresponding hex nuts, making it an ideal choice for assembling garden furniture, building pergolas, or fixing fence panels.
Anti-Twist Square Neck: Designed to prevent the bolt from spinning freely once inserted into timber, allowing for easier tightening of the nut without requiring a second tool to hold the bolt head.
Zinc-Plated Finish: Provides enhanced corrosion resistance, making these bolts suitable for both indoor and outdoor applications where exposure to elements is a factor, such as garden structures.
M6 x 40mm Dimensions: Features an M6 thread diameter and a 40mm length, offering a versatile size for various timber-to-timber connections.
Low Load Bearing Design: Optimized for applications where the joined components do not bear significant weight or structural stress, ensuring reliable performance within its specified use.
Complete Pack: Each package contains 10 coach bolts along with their matching hex nuts, providing a ready-to-use solution for your fastening needs.
Versatile Application: Suitable for a wide range of low load-bearing timber projects, from garden furniture to fencing.
Easy Installation: The square neck design simplifies installation by preventing bolt rotation, requiring only a single wrench for tightening.
Durable Finish: Zinc-plating offers good resistance against rust and corrosion, extending product life in various environments.
Convenient Pack Size: Comes in a 10-pack, ideal for small to medium-sized projects.
Reliable Fastening: Provides strong, secure joints for timber-to-timber connections within its load limits.
Low Load Bearing Only: Not suitable for high-stress structural applications or joining heavy load-bearing components.
Requires Pilot Hole: A pre-drilled pilot hole is necessary for proper installation, adding an extra step to the process.

The Forgefix M6 x 40 Coach Bolt & Nut excels in creating strong, reliable timber-to-timber joints for low load-bearing structures. Its primary strength lies in its square neck design, which firmly beds into the timber, preventing the bolt from rotating during tightening. This feature significantly streamlines assembly, allowing you to secure connections quickly and efficiently using just a single wrench on the hex nut.
Garden Furniture Assembly: Ideal for putting together wooden benches, tables, or chairs, ensuring robust and weather-resistant connections.
Pergola and Trellis Construction: Provides sturdy fastening for the framework of garden pergolas and trellises, designed to support climbing plants without critical structural loads.
Fence Panel Installation: Effective for attaching fence panels to posts or securing sections of wooden fencing.
Timber Joist Construction (Light Duty): Suitable for light-duty joist work where the overall structure is not under heavy stress.
Decking Borders and Edging: Can be used to secure decorative borders or edging around decking areas.
The zinc-plated finish means these bolts can withstand typical outdoor conditions, offering good resistance to rust and corrosion. For optimal performance, ensure you drill an appropriately sized pilot hole (slightly smaller than the bolt shank but larger than the threaded section) to allow the square neck to embed properly without splitting the timber.
Prepare Materials: Ensure your timber pieces are cut to size and aligned correctly.
Drill Pilot Hole: Using a drill bit slightly smaller than the bolt's shank (the smooth part below the head) but large enough to allow the threaded section to pass through, drill a pilot hole through both pieces of timber. The hole should be slightly smaller than the square neck so the neck can bite into the wood.
Insert Bolt: Push the coach bolt through the pre-drilled hole from the 'head' side. Ensure the square neck of the bolt embeds firmly into the timber. You may need to tap it gently with a hammer to fully seat the square neck.
Attach Nut: Place the 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. The square neck will prevent the bolt from rotating.
Primary Use: Exclusively designed for joining timber to timber connections.
Other Materials: Can be used to join timber to other materials (e.g., thin metal brackets) provided the other material is adequately pre-drilled to accommodate the bolt shank and a washer is used under the nut for better load distribution.
Load Bearing: Compatible only with low load-bearing applications. Do not use for critical structural elements or where significant weight or tension will be applied.
Storage: Store unused bolts and nuts in a dry, cool environment to preserve the zinc plating and prevent premature corrosion.
Cleaning: If bolts become dirty, wipe them with a damp cloth and dry immediately. Avoid abrasive cleaners that could damage the zinc coating.
Inspection: Periodically inspect installed bolts in outdoor environments for any signs of corrosion or loosening. Tighten nuts if necessary.
