FAQs
What screws do you use to screw down a subfloor?
For subfloor installation, use deck screws or subfloor screws specifically designed for wood-to-wood fastening. These screws usually feature a self-drilling tip and a coarse thread that grips plywood or OSB firmly. A common choice is #8 or #10 screws, coated to resist corrosion. Avoid drywall screws—they’re brittle and can snap under floor movement. Using subfloor-rated screws ensures a strong, squeak-free connection that can handle structural stress and humidity changes.
Is it better to nail or screw subfloor?
While nailing is faster, screwing is the better long-term option. Screws provide superior holding power and reduce the risk of squeaky floors caused by nail loosening over time. Nails can lift slightly as the wood expands and contracts, whereas screws lock the subfloor tight to the joists. For professionals seeking the most secure bond, a screw gun with collated subfloor screws delivers both efficiency and durability—ideal for new construction and remodeling alike.
What is the best screw length for 3/4 subfloor?
For 3/4-inch subfloor panels, the recommended screw length is 1-5/8 inches to 2 inches. This ensures the screw penetrates at least 1 inch into the floor joist for maximum hold. Shorter screws may not secure the panel properly, while overly long screws can pierce through or split the joist. Always check the manufacturer’s specifications for both the screws and the subflooring material to ensure optimal fastening strength.
What gauge nails for subfloor?
If you choose to nail instead of screw, use 8d ring-shank nails (typically 0.131 inches in diameter and 2.5 inches long). Ring-shank nails grip better than smooth-shank versions, minimizing the chance of movement and squeaks. For pneumatic nailers, select subfloor-rated fasteners to ensure compliance with building codes. However, even with high-quality nails, screws still offer a stronger and quieter floor over time.
Conclusion
Choosing the best screw gun for subfloor work can transform how you build floors—faster installation, tighter joints, and fewer squeaks. Whether you’re tackling a small home project or professional construction, using the right screw gun and fasteners ensures your subfloor stays solid for decades. Screw once, do it right, and enjoy the silence underfoot.
