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.
