Designed for professional contractors and DIY enthusiasts alike, these DIYUK 45mm drywall screws are engineered for robust wood-to-wood and drywall-to-wood fastening. Their primary benefit is the time-saving self-drilling point that eliminates the need for pilot holes, though users should be aware that the black phosphate coating, while corrosion-resistant, may be susceptible to scratching during aggressive installation with high-torque impact drivers.

These screws are treated with a black phosphate coating which is designed for interior use. They are not recommended for long-term outdoor exposure.
No, the screws feature a sharp piercing point designed to penetrate wood without a pilot hole.
A standard Phillips (PH2) screwdriver bit is compatible with these screws.
No, these are designed for wood-to-wood and drywall-to-wood applications. For metal studs, you should use fine-thread drywall screws.
This pack contains 200 individual screws.
Ensure you are using a sharp, correctly sized PH2 bit and reduce the torque setting on your drill.
Apply slightly more downward pressure at the start or check that the wood surface is not overly hardened or glazed.
Use a drywall dimpler bit or adjust the clutch settings on your drill to stop at the correct depth.
To ensure optimal results, always use a high-quality PH2 driver bit that matches the screw head perfectly; this reduces the risk of cam-out and head stripping. While these screws are rust-resistant due to their phosphate coating, they are designed for internal use. If using them in high-moisture areas like basements or garages, ensure the space has adequate ventilation to maintain the integrity of the coating. For best results in wood-to-wood connections, ensure the timber is free of knots that might deflect the screw tip. Store the remaining screws in a dry, cool environment to prevent moisture accumulation in the box.
