Strong-Drive® SDCF TIMBER-CF Screw (Black E-Coat)

The newly redesigned 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.

Key Features
  • Flat head with nibs helps countersink the screw for a flush finish
  • Heavy-duty, fully threaded shank provides strength, with superb withdrawal resistance
  • SawTooth point for fast start and easy driving
  • Black e-coat finish provides a construction-durable nonmetallic coating for corrosion resistance in interior dry-service applications
