Description
Overview:
These Metric Coach Bolts, Zinc Plated, M6 x 40, are steel fasteners for timber-to-timber or timber-to-metal fixings on construction and garden machinery projects. Each bolt has a domed cup head with a square neck that bites into the wood to prevent spinning while you tighten the nut. The M6 coarse thread (approx. 1.0 mm pitch) provides a reliable hold, and the 40 mm length suits medium‐thickness timber sections, hardware brackets and fittings. The bright zinc-plated finish offers enhanced corrosion resistance for indoor and general outdoor use. Supplied as a pack of 100 with matching hex nuts, they are suitable for fencing, decking, gates, sheds, machinery guards, jigs and fixtures across trade and DIY tasks. Use with a 10 mm spanner or socket on the nut side.
Key Features:
- M6 x 40 mm steel coach bolts with nuts for secure timber fixings
- Zinc-plated finish for improved corrosion resistance and long service life
- Domed cup head with square neck prevents bolt rotation during tightening
- Coarse ISO metric thread for reliable clamping and easy assembly
- Supplied in a pack of 100 for efficient site or workshop use
- Smooth low-profile head is snag-resistant and neat in visible installations
- Compatible with common timber brackets, plates and hangers
- Fits standard 10 mm AF spanners/sockets on the nut side

- Versatile for construction, maintenance and equipment mounting on wood
Typical Applications:
Fixing timber to timber or timber to metal in fencing, decking, pergolas, gates, sheds, formwork, benches, play equipment, tool stations, machinery guards and storage racks. Ideal where a smooth, domed head is preferred on the exposed face and tightening is performed from the nut side. Use with washers where needed to spread load on softer woods.
