The Unifix Coach Screws (M10 x 150) are ideal for carpenters, builders, and DIY enthusiasts requiring high-strength structural fastening in heavy-duty wood applications. These screws deliver exceptional grip and long-term stability due to their robust design and adherence to DIN 571 standards. While they provide excellent corrosion resistance, they are specifically engineered for wood-to-wood or wood-to-masonry applications (with appropriate wall plugs) and may require pre-drilling to prevent timber splitting.

Yes, the finish provides effective corrosion resistance suitable for outdoor wood structures.
Yes, these require a socket or spanner that matches the M10 hexagon head profile.
DIN 571 is a technical standard for hexagon head wood screws that ensures specific dimensional and performance requirements are met.
It is strongly recommended to pre-drill to prevent splitting the timber and to make the driving process easier.
No, these are designed specifically for wood applications and are not threaded for metal fastening.
Ensure a pilot hole has been drilled to the correct depth and diameter.
Use a high-quality, non-worn socket and ensure it is fully seated on the screw head before applying torque.
Use a larger pilot hole or ensure you are not installing too close to the edge of the timber beam.
To install these screws, identify the correct socket size that fits the M10 hexagon head. Always mark your fastening points clearly before drilling to ensure alignment. If you are securing timber to brick or stone, you must use high-quality heavy-duty wall plugs compatible with M10 screws. To maintain the integrity of the finish, avoid overtightening with excessive force which might strip the screw threads or damage the protective coating. Regularly inspect the connection points every few years in outdoor settings to ensure the wood has not shrunk, which may require a simple re-tightening.
