This partially threaded screw delivers exceptional pull-together force and load capacity across a wide range of engineered wood and multi-ply lumber assemblies. The black e-coat electrocoating finish provides a friction-reducing, nonmetallic surface that makes driving easier while also meeting corrosion resistance requirements for fire-retardant treated (FRT) lumber. Whether you are working on timber framing, post frame construction, factory-built or modular buildings, or structural composite lumber connections, this fastener is designed to perform without the need for predrilling in most applications.\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 surface approved for FRT lumber and corrosion resistance (ICC-ES AC257 Exposure Condition 3), reducing drive torque while protecting against corrosion in interior and dry-service environments\u003c\/li\u003e\n\u003cli\u003eOptimized hardness profile - mitigates external hydrogen embrittlement issues and meets CSA O86:24 requirements, giving builders confidence in structural integrity and long-term performance in timber construction\u003c\/li\u003e\n\u003cli\u003eFlat head with underhead nibs - helps countersink cleanly for a flush surface finish, reducing the need for additional surface prep and delivering a professional result on exposed timber faces\u003c\/li\u003e\n\u003cli\u003eDeep T40, 6-lobe recess - provides a secure, slip-resistant drive connection and includes a driver bit in the package so you can start work immediately without sourcing separate tooling\u003c\/li\u003e\n\u003cli\u003eHeavy-duty shank - adds strength and durability to the fastener body, supporting high structural loads in mass timber and engineered wood connections\u003c\/li\u003e\n\u003cli\u003eShank knurl - aids in torque reduction during installation, making it easier to drive these screws consistently and reducing fatigue during high-volume framing work\u003c\/li\u003e\n\u003cli\u003eType-17 point - ensures fast, clean starts, reduces installation torque, and eliminates the need for predrilling in most applications, saving time on structural timber jobsites\u003c\/li\u003e\n\u003cli\u003ePartial thread design - pulls structural members together with superior holding power, ideal for wood-to-wood fastening where tight clamping force is critical\u003c\/li\u003e\n\u003cli\u003eLength: 140 mm (5 1\/2 in.) with a thread length of 3 1\/8 in. - sized for solid engagement in thick timber members and multi-ply engineered wood assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy This Product\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt specifically for mass timber and CLT construction - the SDCP Timber-CP screw addresses the unique structural demands of cross-laminated timber and engineered wood applications where standard wood screws may not meet load or embrittlement requirements.\u003c\/li\u003e\n\u003cli\u003eReduces installation effort without compromising performance - the combination of black e-coat's low friction surface, shank knurl, and Type-17 point all work together to lower drive torque, letting crews work faster and with less fatigue across large timber framing projects.\u003c\/li\u003e\n\u003cli\u003eCompliant with current engineering standards - the optimized hardness profile meets CSA O86:24 hydrogen embrittlement requirements and the e-coat finish is approved under ICC-ES AC257 Exposure Condition 3, helping project teams satisfy structural and code compliance requirements.\u003c\/li\u003e\n\u003cli\u003eDesigned for dry-service interior environments - the black e-coat finish is specifically rated for interior and dry-service conditions including FRT lumber, making this screw the right choice for factory-built, modular, and residential wood construction where corrosion exposure must still be managed.\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 5 1\/2 in.
