Simpson Strong-Tie SDCF8X140-R50 Strong-Drive® SDCF TIMBER-CF Screw — 0.315 in. x 5-1/2 in. T40, E-Coat® (50-Qty) (Pack of 360)

The redesigned Simpson Strong-Tie® Strong-Drive® SDCF Timber-CF screw is a structural fastener designed for cross-laminated timber (CLT), mass timber construction and general interior applications, providing uncompromised strength for demanding applications. The large flat head with underhead nibs enables clean countersinking and a flush finish. 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.
