The redesigned SDCFC TIMBER-CFC screw combines a fully threaded shank for maximum withdrawal resistance with a compact cylinder head that delivers a clean, professional finish whether left exposed or countersunk. The proprietary SawTooth point bites into wood quickly, reducing installation torque and eliminating the need for predrilling in most applications - making it a practical choice for high-volume timber framing, beam reinforcement, and cross-laminated timber fastening. The black e-coat electrocoating finish enhances aesthetics while providing a construction-durable, nonmetallic barrier against corrosion in interior dry-service conditions, and the optimized hardness profile helps mitigate the risk of brittle fracture for reliable long-term performance.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCompact cylinder head design - helps countersink the screw flush for a clean, polished finish in exposed timber applications or a concealed look when fully set\u003c\/li\u003e\n\u003cli\u003eHeavy-duty, fully threaded shank - provides superb withdrawal resistance along the entire shank length, maximizing holding power in large timber members and multi-ply engineered wood\u003c\/li\u003e\n\u003cli\u003eSawTooth point -

the fully threaded shank maximizes withdrawal resistance exactly where heavy timber and glulam connections demand it most, making this screw a purpose-built solution rather than a general-purpose fastener\u003c\/li\u003e\n\u003cli\u003eEliminates predrilling in most applications - the SawTooth point reduces installation torque and speeds up driving, cutting labor time significantly on large timber framing and beam reinforcement projects\u003c\/li\u003e\n\u003cli\u003eBlack e-coat finish suits exposed timber aesthetics - the nonmetallic electrocoating provides corrosion resistance for interior dry-service use while blending cleanly with dark wood tones, making it a practical choice for visible architectural timber applications\u003c\/li\u003e\n\u003cli\u003eIncludes a T40 6-lobe driver bit - the screw ships with a compatible driver bit so installers can get started immediately without sourcing additional accessories separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Simpson Strong-Tie\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Strong-Drive SDCFC TIMBER-CFC Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 13-3\/4 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter:\u003c\/strong\u003e 0.230 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter:\u003c\/strong\u003e 0.400 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length:\u003c\/strong\u003e 13-3\/8 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type:\u003c\/strong\u003e Cylinder Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type:\u003c\/strong\u003e T40 6-Lobe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type:\u003c\/strong\u003e SawTooth Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating:\u003c\/strong\u003e E-coat Electrocoating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e E-coat Electrocoating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cstrong\u003e\n\u003ch3\u003eAvailable Pack Options\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSDCFC8X350-R30:\u003c\/strong\u003e 30 Pk -
