The TurboDrive Wood Screw (4mm x 40mm) is designed for DIY enthusiasts, woodworkers, and contractors who require a reliable fastening solution for general construction and furniture assembly. These premium yellow-coated screws provide excellent holding power and corrosion resistance in indoor applications, though they are not intended for heavy-duty structural load-bearing projects.

These screws are intended primarily for indoor use. They offer minimal protection against rust and should not be used in external environments.
While not always necessary in soft woods, pre-drilling a pilot hole is highly recommended when working with hardwoods to prevent splitting.
Each pack contains 100 screws.
Yes, they are compatible with standard power drills and impact drivers, provided you use the correct torque settings.
These feature a double-countersunk head, which allows the head to sit flush with the wood surface.
Ensure you are using the correct size driver bit and maintain downward pressure while driving the screw.
Drill a pilot hole slightly smaller than the 4mm screw diameter before inserting the fastener.
Check that the screw is aligned straight and consider applying a small amount of wax or soap to the threads.
For the best results, use a standard screwdriver bit compatible with the screw head design. Always ensure that your drill or driver is set to the correct torque to avoid stripping the thread in softer materials. While the screws have a protective yellow coating, avoid using them in high-moisture outdoor environments where rain or humidity can lead to oxidation. Store the remaining screws in a dry, cool place to prevent the coating from degrading over time.
