Cross-Laminated Timber Screws
0.390" x 39-3/8" Strong-Drive SDCFC Timber-CF Screw - Yellow Zinc, Pkg 50
Specifications
The Simpson Strong-Tie® Strong-Drive® SDCFC Timber-CFC Screw is built tough for wood projects like mass timber, cross-laminated timber (CLT), or other heavy framing jobs.
These extra-long screws sink in smooth and stay strong. The compact cylinder head sits flush with the surface, giving your project a clean finish without bulky hardware sticking out. The fully threaded design grabs tight for maximum holding power, while the sharp tip starts fast and drives easy with less splitting.
Coated with interior-grade yellow zinc, the SDCFC screw is made for dry, indoor projects where strength and reliability matter most.
Key Features
- Made for Large Projects – Perfect for CLT, mass timber, and other heavy-duty builds.
- Smooth, Flush Finish – Compact cylinder head sinks cleanly into the wood for a neat look.
- Maximum Grip – Fully threaded shank locks in tight for superior holding strength.
- Reliable Drive – Deep 6-lobe recess (T50) for steady bit grip and less stripping.
- Built for Indoors – Yellow-zinc coating provides protection in dry, interior conditions.
