Create robust, long-lasting joints in timber and masonry with our M6 Zinc-Plated Hex Head Coach Screws. Engineered for superior strength and grip, these heavy-duty screws are the professional's choice for structural woodwork and the DIYer's secret to a secure, reliable build, from garden decking to indoor joinery.


Key Features & Benefits


  • Heavy-Duty Holding Power: A deep, coarse thread provides exceptional grip and high pull-out resistance in wood, far exceeding the strength of standard screws for critical load-bearing connections.

  • High-Torque Hex Head: The 10mm hexagonal head is designed for use with a standard spanner or socket driver, allowing for high torque application to create a tight, secure, and lasting fit without cam-out.

  • Corrosion Resistant Finish: A bright zinc plating (BZP) is applied to the steel core to provide a protective barrier against rust and corrosion, ensuring durability for both indoor and sheltered outdoor projects.

  • Professional Grade Standard: Manufactured in strict accordance with DIN 571 specifications, guaranteeing consistent dimensional accuracy and quality for reliable, predictable performance on any job site.

  • Versatile Application: The ultimate fastener for timber-to-timber connections. Also ideal for securing fixtures into brick or concrete when used in conjunction with a compatible nylon wall plug.


Perfect for a Wide Range of Projects


Whether you are a professional builder or a weekend DIY enthusiast, these M6 coach screws are the ideal solution for your most demanding projects:

  • Structural Timber Work: An essential component for roof trusses, floor joists, timber framing, and other structural applications where strength is paramount.

  • Garden & Landscaping: The go-to fastener for building robust decks, pergolas, fences, gates, and retaining walls made from railway sleepers.

  • Heavy Joinery & Assembly: Use for constructing solid workbenches, attaching heavy furniture legs, and other woodworking projects that require more holding power than a standard screw can provide.

  • Masonry Fixing: Securely fasten timber battens, brackets, gate posts, and other fixtures to brick or concrete walls by pairing the screw with an nylon plug for a powerful anchor.


Installation Guide for a Professional Finish


Following these steps will ensure a strong, secure fixing and prevent damage to your materials.

  1. Mark Your Position: Use a pencil to clearly mark the exact centre point where the screw will be driven.

  2. Drill a Pilot Hole: Pre-drilling a pilot hole is essential to prevent the wood from splitting, especially near edges, and to ensure the screw drives in straight. The pilot hole size depends on the wood density:

  • For Softwood (e.g., Pine, Spruce): Use a 3mm drill bit (approximately 50% of the screw's 6mm diameter).

  • For Hardwood (e.g., Oak, Beech): Use a 4.5mm drill bit (approximately 75% of the screw's 6mm diameter).

  1. Drive the Screw: Use a 10mm spanner, ratchet with a 10mm socket, or an impact driver with a 10mm hex driver bit. Drive the screw until the head is seated firmly against the surface. For a superior finish and to distribute the clamping force, it is highly recommended to place an M6 washer under the head before driving.
