Simpson Strong-Tie SDCF8X140-R50 - Strong-Drive SDCF TIMBER-CF Screw , 0.315" x 5-1/2" T40, E-Coat 50 ct

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.
