With a fully threaded shank for maximum withdrawal resistance, a compact cylinder head for a clean exposed or countersunk finish, and a black e-coat electrocoating finish that resists corrosion in interior dry-service environments, this screw delivers reliable long-term performance in timber framing, glulam fastening, beam reinforcement, and cross-laminated timber work. The redesigned SawTooth point enables fast starts and easy driving, eliminating the need for predrilling in most applications and reducing installation torque for faster, more efficient jobsite performance.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact cylinder head\u003c\/strong\u003e -

this screw's 17 in. length and fully threaded shank make it the right fastener for mass timber, glulam, heavy timber framing, and multi-ply engineered wood assemblies where standard screws fall short\u003c\/li\u003e\n\u003cli\u003eNo predrilling required in most applications - the SawTooth point dramatically reduces installation time and labor on large timber projects, making it practical for both small crews and high-volume structural work\u003c\/li\u003e\n\u003cli\u003eAesthetic and structural in one fastener - the compact cylinder head allows the screw to sit flush or countersink cleanly, making it suitable for exposed structural connections where appearance matters alongside performance\u003c\/li\u003e\n\u003cli\u003eEngineered for long-term reliability - the optimized hardness profile combined with the e-coat finish addresses the risk of brittle fracture and corrosion in interior dry-service conditions, supporting durable connections in engineered wood, beams, and Simpson Strong-Tie connector installations\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 17 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 16 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Type:\u003c\/strong\u003e T40 6-Lobe\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type:\u003c\/strong\u003e Cylinder Head\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\u003eSDCFC8X430-R25:\u003c\/strong\u003e 25 Pk -
