When you need to fasten wood, plywood, or OSB directly to steel framing, without pre‑drilling, the Simpson Strong‑Tie F10C144WDB Self‑Drilling Wafer‑Head Screw with Wings is built for the job. This precision‑engineered screw features a self‑drilling point with break‑off wings that clear the hole and prevent climbing up the shank, while the low‑profile wafer head offers clean seating with full bearing. Made of 410 stainless steel and full‑length machine‑threaded, it’s optimized for professional contractors and DIYers working wood‑to‑steel, panel‑to‑stud, or sheet‑metal‑to‑structural connections.

Key Features

• Self‑Drilling Efficiency: #3 drill point eliminates the need for pre‑drilling into steel studs or track.
• Winged Design: Wings ahead of the drill point bore a clearance hole through wood or panel, then snap off when they hit steel, preventing material climb.
• Low-Profile Wafer Head: Provides a broad bearing surface and clean, flush finish without overdriving.
• Full-Length Machine Thread: Improves pull‑through resistance and ensures strong load transfer.
• Durable Construction: Made from Type 410 stainless steel with coating for additional corrosion resistance (interior or dry-use applications).

Applications

• Attaching wood panels, plywood, or OSB to steel studs or track.
• Fastening sheet goods to cold‑formed steel framing components.
• Used in commercial build‑outs, interior framing, remodels, and tenant finishes.
• Excellent for projects that require fast, reliable wood-to-steel fastening with a low-profile finish.

Installation

1. Select a screw variant that ensures full penetration into the steel backing with full thread engagement.
2. Use a #2 Phillips or appropriate drive bit in a power driver with clutch control to avoid overdriving.
3. Drive screw perpendicular to surface; allow wings to create the clearance hole and snap off as screw reaches steel.
4. Ensure the wafer head sits flush with the wood or panel surface.
5. Follow substrate thickness and spacing guidelines as recommended; avoid use in corrosive or high-moisture environments.
