Specifications
The Simpson Strong-Tie® Strong-Drive® SDCF Timber-CF Screw is engineered for strength and reliability in cross-laminated timber (CLT), mass timber, and other demanding wood construction applications. Available in multiple lengths and diameters, these fully threaded structural fasteners deliver exceptional withdrawal resistance and holding power, making them the trusted choice for large-scale wood assemblies.
Each screw features a flat head with underhead nibs for clean countersinking, ensuring a flush finish on exposed surfaces. The yellow-zinc interior-grade coating provides corrosion protection, while the proprietary point design ensures fast starts and smooth driving. Deep 6-lobe recesses reduce cam-out and extend bit life, keeping your installs efficient and consistent.
