The Forgefix Coach Screw is an essential fastener for professional tradespeople and DIY enthusiasts working on heavy-duty timber construction or masonry installations. Designed for maximum torque and high pull-out resistance, these zinc-plated screws offer exceptional durability and speed of installation; however, they require pre-drilling when working with dense materials to prevent timber splitting.

Yes, pre-drilling is highly recommended for hardwoods and masonry to prevent timber splitting and to ensure the screw can reach its full depth.
Yes, the zinc-plated finish provides good corrosion resistance for outdoor installations, though they should be monitored in highly corrosive coastal areas.
You should use a socket driver or a spanner that fits the hexagonal head of the M12 screw.
When paired with the appropriate high-quality masonry wall plug, these are excellent for fastening timber to concrete or brickwork.
The single thread is engineered for high pull-out resistance, meaning the screw holds much more securely under tension than multi-thread alternatives.
Ensure a pilot hole has been drilled; the pilot diameter should be approximately 70-80% of the screw shank diameter.
Move the fixing point further from the edge or use a smaller diameter pilot hole to reduce internal pressure.
Verify that your socket driver is fully seated on the hex head and is the correct metric size.
To ensure the best performance, always select the correct socket size for the hex head. If installing into masonry, ensure you use a masonry drill bit of the correct diameter for your wall plug. When working with treated timber, ensure the drill bit is sharp to prevent tear-out. These screws are designed for outdoor use due to their zinc plating; however, in extremely aggressive or coastal environments, inspect them periodically for signs of oxidation. If the zinc coating is damaged during installation, a touch of cold-galvanizing spray can help maintain the protective barrier.
