Product Description
Simpson Strong-Drive SDCFC TIMBER-CFC Screw - 0.390 in. x 15 in., T50, E-Coat by Simpson Strong-Tie is a heavy-duty structural wood screw engineered for demanding timber construction applications including mass timber, glulam beams, cross-laminated timber, and multi-ply engineered wood fastening. The redesigned SDCFC Timber-CFC screw combines a fully threaded shank, a compact cylinder head, and a SawTooth point to deliver fast installation, exceptional withdrawal resistance, and a clean finished appearance - whether the head is left exposed or countersunk. The black e-coat electrocoating finish provides a construction-durable, nonmetallic barrier suited for interior dry-service environments while also enhancing the screw's overall appearance in exposed timber applications.
Key Features
- Compact cylinder head design - helps countersink the screw for a clean, professional finish whether left exposed or set flush with the surface
- Heavy-duty, fully threaded shank - maximizes contact along the entire fastener length, delivering superb withdrawal resistance for long-term structural integrity in large timber members
- SawTooth point - starts fast and drives easily, reducing installation torque and eliminating the need for predrilling in most timber applications
- Black e-coat electrocoating finish - provides a construction-durable, nonmetallic coating that resists corrosion in interior dry-service applications while giving a clean, aesthetic appearance on exposed timber
- Deep T50 6-lobe recess - creates a secure, high-torque engagement with the driver bit, reducing cam-out and improving control during installation into dense wood members
- Optimized hardness profile - works alongside the e-coat finish to help mitigate the risk of brittle fracture, supporting reliable long-term structural performance
- Compliant with CSA O86:24 hydrogen embrittlement requirements - meets Canadian structural wood design standard requirements for confidence in code-compliant installations
- 15 in. length (380 mm) with 14 5/8 in. thread length - provides deep penetration and substantial grip into large engineered wood and heavy timber members
Why This Product
- Designed specifically for mass timber, glulam, and cross-laminated timber - the 15 in. fully threaded shank penetrates deeply into large members where standard screws fall short, making it the right tool for heavy structural wood connections
- Eliminates predrilling in most applications - the SawTooth point reduces installation time and labor on timber framing, beam reinforcement, and multi-ply engineered wood projects without compromising holding power
- Black e-coat finish suits exposed timber aesthetics - the nonmetallic electrocoating provides corrosion resistance for interior dry-service conditions while the black color complements the natural look of visible heavy timber construction
- Meets CSA O86:24 hydrogen embrittlement compliance - gives contractors and engineers confidence that this fastener satisfies current structural wood design standards for demanding timber applications
