Simpson Strong-Tie SDCFC8X120-R50 Strong-Drive® SDCFC TIMBER-CFC Screw — 0.315 in. x 4-3/4 in. T40, E-Coat® (50-Qty)

The redesigned Simpson Strong-Tie® Strong-Drive® SDCFC Timber-CFC screw is a robust structural fastener for demanding applications involving large members such as mass. A fully threaded shank provides withdrawal resistance, and the compact cylinder head creates a clean finish when left exposed, or a concealed finish when countersunk. The SawTooth® point ensures fast starts, reducing installation torque and eliminating the need for predrilling in most applications. The black e-coat finish enhances aesthetics and, along with the optimized hardness profile, helps mitigate risk of brittle fracture for reliable, long-term performance.

This Simpson product is designed for construction, connector, fastening, anchoring, and structural applications where dependable performance, durability, and jobsite-ready installation matter.
