The Forgefix M6 x 75 Coach Bolt & Nut pack is an essential fixing for DIY enthusiasts and professionals working with timber. This 10-pack provides strong, anti-twist fastenings ideal for low load bearing applications in outdoor structures like garden furniture, pergolas, and fence panels. While offering robust assembly and resistance to elements, it's crucial to remember their limitation to lower stress connections, making them perfect for specific, appropriate construction tasks.
Square Neck Design: Features a square neck just under the bolt head which beds into timber, effectively preventing the bolt from twisting when the nut is tightened.
Zinc Plated Finish: Provides enhanced resistance against rust and corrosion, making these bolts suitable for outdoor use and ensuring longevity against various weather elements.
M6 Thread Size: Indicates a 6mm nominal diameter for the bolt's thread, suitable for a range of light to medium duty timber applications.
75mm Length: Offers ample length for joining various thicknesses of timber components securely.
Pack of 10 with Hex Nuts: Each pack contains 10 coach bolts and 10 corresponding hex nuts, providing a complete solution for multiple fastening points.
Versatile Application: Ideal for joining timber to timber, timber joist construction, and assembling garden structures such as furniture, pergolas, and fence panels.
Anti-Twist Stability: The square neck prevents the bolt from rotating, simplifying installation and ensuring a secure, tight fastening.
Corrosion Resistance: Zinc plating offers good protection against rust, making them suitable for external use and extending product life.
Complete Fixing Solution: Each pack includes both bolts and hex nuts, eliminating the need for separate purchases.
Wide Range of Timber Applications: Excellent for various timber-to-timber connections, especially in outdoor or garden projects.
Durable Construction: Designed to withstand exposure to diverse weather conditions.
Low Load Bearing: Not suitable for high-stress or heavy-duty structural applications where significant loads or forces are present.
Requires Pilot Hole: A pilot hole must be pre-drilled, which adds a step to the installation process compared to self-drilling screws.

The Forgefix M6 x 75 Coach Bolt & Nut is engineered for reliable performance in low load bearing timber constructions. Its primary strength lies in its ability to securely join timber sections without the bolt spinning during tightening, thanks to the square neck. This feature is particularly beneficial when working with softer woods where a conventional bolt head might dig in or allow rotation.
Garden Furniture Assembly: Use these bolts to assemble wooden benches, tables, or chairs for a sturdy and weather-resistant connection.
Pergola and Trellis Construction: Ideal for fixing crossbeams or uprights where aesthetic and stable connections are needed without extreme load requirements.
Fence Panel Fixing: Secure fence panels to posts, ensuring they remain robust against wind and general wear.
Decking Substructure (Light Duty): Can be used for non-primary structural elements of decking, like attaching smaller joists or support battens where overall load is distributed.
Children's Play Equipment (Non-Structural): Suitable for connecting non-load-bearing components like decorative panels or steps on smaller playhouses.
Always ensure the application aligns with the 'low load bearing' characteristic of these fixings. For critical structural elements or applications under significant stress, alternative fasteners designed for higher loads should be considered.
Drill Pilot Hole: Using a suitable wood drill bit, create a pilot hole through both timber pieces to be joined. The diameter of this hole should be slightly larger than the bolt's shaft (e.g., 6.5mm or 7mm for an M6 bolt) but smaller than the square neck to allow it to bite into the wood.
Insert Bolt: Push the coach bolt through the pilot hole from the side where the bolt head will sit. Ensure the square neck passes through the first piece of timber and bites firmly into the second piece, preventing rotation.
Attach Nut: Place the hex nut onto the threaded end of the bolt protruding from the other side. You may wish to use a washer (not included) between the nut and the timber surface for increased bearing area and to prevent the nut from digging into the wood.
Tighten: Using an appropriate spanner or wrench, tighten the hex nut until the connection is secure. The square neck should prevent the bolt from turning, allowing for effective tightening.
Materials: Primarily designed for joining timber to timber.
Dimensions: The M6 thread and 75mm length are suited for timber sections that, when combined, are slightly less than 75mm thick (allowing for the nut and some thread protrusion).
Environment: Zinc plating makes them compatible with outdoor, exposed environments, offering good resistance to moisture and weather.
Inspection: Periodically inspect outdoor installations for any signs of loosening or corrosion, especially after harsh weather.
Cleaning: If dirt or grime accumulates, clean with a damp cloth. Avoid harsh chemicals that could damage the zinc plating.
Retightening: If any connections feel loose over time, carefully retighten the nuts. Over-tightening can damage the timber.
Storage: Store unused bolts and nuts in a dry environment to maintain their zinc plating and prevent premature corrosion.
