Product Description
Simpson Strong-Drive SDCFC TIMBER-CFC Screw - 0.390 in. x 9-1/2 in., T50, E-Coat by Simpson Strong-Tie is a heavy-duty structural wood screw engineered for demanding large-member timber connections including mass timber, glulam beams, and cross-laminated timber assemblies. The fully threaded shank delivers exceptional withdrawal resistance, while the compact cylinder head and black e-coat finish produce a clean, professional appearance whether left exposed or countersunk. Designed for wood-to-wood fastening, beam reinforcement, and timber framing, this screw eliminates the need for predrilling in most applications - saving time and labor on structural installations.
Key Features
- Compact cylinder head - helps countersink the screw for a clean finish when exposed or concealed, ideal for visible structural connections in mass timber and heavy timber applications
- Heavy-duty, fully-threaded shank with 9 in. thread length - provides superior withdrawal resistance across the full fastened length, maximizing structural holding power in large wood members
- SawTooth point - enables fast starts and easy driving while reducing installation torque, eliminating the need for predrilling in most applications and speeding up workflow
- Black e-coat electrocoating finish - delivers a construction-durable nonmetallic coating for corrosion resistance in interior dry-service conditions while enhancing aesthetics in exposed timber applications
- Deep T50 6-lobe recess drive - provides a secure, slip-resistant bit engagement that reduces cam-out and allows confident driving into dense timber members
- Optimized hardness profile - works together with the e-coat finish to mitigate the risk of brittle fracture, supporting reliable long-term structural performance
- Compliant with CSA O86:24 hydrogen embrittlement requirements - meets rigorous engineering standards for structural timber fasteners, providing confidence in code-sensitive applications
- 0.390 in. diameter x 9-1/2 in. length - sized for large structural members where a robust, high-capacity fastener is required
Why This Product
- Purpose-built for mass timber and heavy timber construction - approved applications include cross-laminated timber, glulam, engineered wood multi-ply fastening, and beam reinforcement where a high-capacity structural screw is essential
- Eliminates predrilling in most applications - the SawTooth point reduces installation torque and drives cleanly into dense wood members, cutting labor time on large framing and timber projects
- Aesthetically compatible with exposed timber designs - the black e-coat finish and countersinking cylinder head produce a clean, finished appearance that suits architectural mass timber and visible structural elements
- Engineered for long-term reliability - the combination of an optimized hardness profile and e-coat electrocoating reduces brittle fracture risk and provides corrosion resistance for interior dry-service environments, backed by CSA O86:24 compliance
