#10 Wood-to-Metal Self-Drilling Screws with Wings — 2 ¾" (40-Pack)

These #10 x 2 ¾" wood-to-metal self-drilling screws with wings are built for fast, secure fastening through mixed substrates where installers need dependable bite into steel after passing through wood-based materials. The cutting wings are designed to clear wood efficiently and then break away upon contacting metal, helping the screw seat tight without binding—ideal for tile backer board and substrate prep workflows.

Key Selling Points

• 2 ¾" length for mixed assemblies: Long enough to fasten through backer board and wood layers into light-gauge steel studs.
• #10 heavy-duty holding power: Strong thread profile for reliable grab in both wood and metal substrates.
• Self-drilling tip: Eliminates pre-drilling in metal, improving speed and consistency on the jobsite.
• Breakaway wings: Ream wood cleanly for smoother driving, then snap off at metal contact for tight, flush seating.
• Contractor-friendly 40-pack: Right-sized for small to medium tile/backer board installs with less waste and fewer reorders.
