The black e-coat electrocoating finish delivers a low-friction, corrosion-resistant surface that reduces driving torque while meeting the demands of fire-retardant treated (FRT) lumber environments. Partially threaded for superior pull-together force, this structural wood screw is built to draw framing members tightly together with outstanding holding power - making it a trusted choice for timber framing, post frame construction, engineered wood assemblies, and factory-built or modular construction projects.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBlack e-coat electrocoating finish - provides a construction-durable, nonmetallic, friction-reducing coating approved for FRT lumber and corrosion resistance (approved for ICC-ES AC257 Exposure Condition 3), so you can drive into treated wood without accelerated corrosion concerns\u003c\/li\u003e\n\u003cli\u003eOptimized hardness profile compliant with CSA O86:24 - mitigates external hydrogen embrittlement, reducing the risk of brittle fracture in structural applications where long-term reliability is critical\u003c\/li\u003e\n\u003cli\u003eFlat head with underhead nibs - countersinks cleanly for a flush, finished surface without additional prep work, saving installation time\u003c\/li\u003e\n\u003cli\u003eDeep T40, 6-lobe drive recess - delivers a secure, cam-out-resistant drive for confident installation; a T40 driver bit is included in the package\u003c\/li\u003e\n\u003cli\u003eHeavy-duty shank with shank knurl - adds strength and durability while reducing torque during driving, making long fasteners easier to install\u003c\/li\u003e\n\u003cli\u003eType-17 point - ensures fast starts, reduces installation torque, and eliminates the need for predrilling in most applications, speeding up the workflow on the job site\u003c\/li\u003e\n\u003cli\u003e300 mm (11 3\/4 in.) length - sized for deep penetration in thick mass timber and multi-ply engineered wood assemblies, providing the grip depth needed for structural connections\u003c\/li\u003e\n\u003cli\u003ePartially threaded design - pulls structural members tightly together for superb clamping and load-carrying capacity in wood-to-wood connections\u003c\/li\u003e\n\u003cli\u003eInterior and dry-service rated - optimized for interior construction environments including CLT, structural composite lumber, and engineered wood systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy This Product\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned specifically for mass timber and CLT construction - the 300 mm length and partial thread profile are engineered to handle the deep penetration and clamping force demands of thick engineered wood and cross-laminated timber assemblies, where standard screws fall short.\u003c\/li\u003e\n\u003cli\u003eThe black e-coat finish reduces driving friction - meaning less torque is required to seat each fastener, reducing installer fatigue and bit wear during large-scale timber framing or post frame projects.\u003c\/li\u003e\n\u003cli\u003eCSA O86:24 hydrogen embrittlement compliance provides peace of mind - the optimized hardness profile is specifically developed to mitigate brittle fracture risk, a critical consideration in structural wood connections subject to long-term loading.\u003c\/li\u003e\n\u003cli\u003eNo predrilling required in most applications - the Type-17 point and low-friction coating work together to simplify installation in engineered wood, structural composite lumber, and general framing scenarios, reducing labor time and tool requirements on site.\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 SDCP TIMBER-CP Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 300 mm (11 3\/4 in.)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter:\u003c\/strong\u003e 0.225 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length:\u003c\/strong\u003e 3 1\/8 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter:\u003c\/strong\u003e 0.575 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type:\u003c\/strong\u003e Flat Head with Nibs\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 Type-17 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\u003eSDCP8X300-R50:\u003c\/strong\u003e 50 Pk -
