The Forgefix Coach Bolt & Nut M10 x 150 pack provides versatile and reliable fastenings primarily for timber-to-timber applications. Designed with a unique square neck, these zinc-plated bolts prevent twisting during installation, ensuring a secure fit for projects like garden furniture, pergolas, and fence panels. While exceptionally strong for their intended use, it's crucial to remember they are best suited for low load-bearing applications.
Square Neck Design: Features a square section beneath the bolt head which beds into timber, preventing the bolt from twisting when the nut is tightened.
Zinc-Plated Finish: Provides good corrosion resistance, making the bolts suitable for outdoor and exposed applications.
M10 Thread & 150mm Length: Standard M10 diameter thread and 150mm length offer versatility for various timber thicknesses.
Timber Application Focus: Specifically designed for securely joining timber to timber, ideal for construction and DIY projects.
Complete Fixing: Each pack includes 10 coach bolts complete with accompanying hex nuts, ready for immediate use.
Durable Construction: Manufactured by Forgefix, ensuring a robust and reliable fastening solution that can withstand outdoor elements.
Twist Prevention: The square neck design ensures the bolt doesn't spin, simplifying installation and providing a more secure connection.
Corrosion Resistance: Zinc-plating makes them suitable for both indoor and outdoor use, resisting rust and degradation.
Versatile Timber Fastening: Excellent for a wide range of timber-to-timber applications, from structural joints to garden constructions.
Complete Pack: Comes with both bolts and hex nuts, eliminating the need to purchase components separately.
Strong for Intended Use: Provides durable and weather-resistant fastenings for suitable projects.
Low Load-Bearing: Specifically designed for low load-bearing applications; not suitable for high-stress structural joints.
Timber Specific: Primarily intended for timber-to-timber connections; less versatile for other material types.

Forgefix Coach Bolts are engineered for straightforward and effective timber construction. Their primary strength lies in their ability to create secure, lasting joints in wooden structures without specialized tools.
Typical Applications:
Garden Furniture Assembly: Ideal for benches, tables, and chairs where strong, weather-resistant joints are required.
Pergola and Trellis Construction: Provides robust connections for timber framework, ensuring stability against outdoor conditions.
Fence Panel Fixing: Securely attaches fence rails to posts or joins panels together, withstanding wind and general wear.
Timber Joist Construction: Used in non-critical, low load-bearing timber frame constructions where rotational stability is key.
How they perform:
The square neck is a key performance feature. When you pre-drill a hole in the timber, slightly larger than the bolt's threaded shaft but snug enough for the square shoulder, the bolt can be hammered or pulled through. As the square neck seats into the timber, it locks the bolt in place, preventing it from rotating while you tighten the nut from the other side. This ensures a tight, professional finish with minimal effort. The zinc plating protects the steel from moisture, making these bolts reliable for outdoor use where exposure to rain and humidity is common, preventing unsightly rust stains and maintaining structural integrity over time.
Prepare Materials: Ensure your timber pieces are cut to size and aligned correctly.
Drill Pilot Hole: Using a drill bit slightly larger than the bolt's threaded shaft (e.g., a 10mm or 11mm drill bit for M10 bolts), drill a pilot hole through both pieces of timber where the bolt will pass. Ensure the hole is straight.
Insert Bolt: Push the coach bolt through the pre-drilled hole. You may need to gently tap the bolt head with a hammer to ensure the square neck fully seats into the timber, preventing it from spinning.
Attach Nut: Place a washer (if using, recommended for larger projects) over the bolt's protruding end, then thread on the hex nut.
Tighten: Use an appropriate spanner or wrench (e.g., 17mm for M10 nuts) to tighten the nut until the joint is secure. Do not overtighten, as this can crush the timber.
Materials: Primarily designed for joining timber to timber. Can also be used to fasten timber to certain thin metal sections or composite materials, provided a suitable pilot hole is drilled and the application is low load-bearing.
Tools: Requires a drill with a wood-suitable drill bit (e.g., an auger bit or spade bit) of appropriate diameter for the M10 bolt, and a spanner or wrench for the M10 hex nut (typically 17mm).
Forgefix Coach Bolts are designed for durability with their zinc-plated finish, requiring minimal maintenance.
Inspection: Periodically inspect outdoor bolted joints for any signs of loosening due to timber shrinkage or expansion, and re-tighten if necessary.
Cleaning: If exposed to harsh conditions, a simple wipe-down with a damp cloth can help remove dirt and extend the life of the zinc plating. Avoid abrasive cleaners or wire brushes that could damage the protective layer.
Storage: Store unused bolts and nuts in a dry environment to maintain their zinc coating and prevent premature corrosion.
