The Unifix Coach Screws (M10 x 130) are professional-grade heavy-duty fasteners designed for construction projects involving wood-to-wood or wood-to-metal connections. Ideal for contractors and DIY enthusiasts who require high-strength structural integrity, these silver-finished screws offer reliable performance in demanding environments; however, they require pre-drilling in hardwoods to prevent material splitting due to their substantial gauge.

These are primarily designed for wood-to-wood or wood-to-metal connections where the screw threads can grip into the wood structure.
For softwoods, you may get away with driving them directly, but pre-drilling is highly recommended for hardwoods to prevent splitting.
You will need a drill with a pilot bit and a socket wrench or an impact driver with the appropriate hex-socket adapter.
DIN 571 is the German industrial standard for hexagon head wood screws, ensuring uniformity in dimensions and head sizing.
They are suitable for standard outdoor use, but for long-term exposure in harsh weather, check if the application requires stainless steel fasteners instead.
Ensure the pilot hole is correctly sized and consider using a soap-based lubricant on the threads.
The pilot hole is too small; enlarge the diameter of your pilot drill bit until the screw drives in without excessive force.
Verify you are using the correct socket size and that the tool is fully seated on the head before applying torque.
To ensure the best results, always measure the thickness of the material and select an appropriate pilot hole bit. For M10 screws, a pilot hole slightly smaller than the core diameter of the screw is recommended to ensure the threads bite effectively without causing the timber to crack.
