This partially threaded screw delivers exceptional holding power and high load capacity, pulling structural members tightly together while its flat head with underhead nibs countersinks cleanly and flush with the surface. The black e-coat electrocoating finish makes this timber screw well suited for fire-retardant treated (FRT) lumber environments and interior dry-service conditions, offering a low-friction, construction-durable solution for demanding structural composite lumber and engineered wood assemblies.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBlack e-coat electrocoating finish - provides a nonmetallic, friction-reducing, and construction-durable coating approved for ICC-ES AC257 Exposure Condition 3, making it compatible with FRT lumber while offering corrosion resistance in interior applications\u003c\/li\u003e\n\u003cli\u003eOptimized hardness profile compliant with CSA O86:24 - mitigates external hydrogen embrittlement risk, helping ensure long-term structural integrity in mass timber and CLT assemblies\u003c\/li\u003e\n\u003cli\u003eFlat head with underhead nibs - allows the screw to countersink cleanly and sit flush with the surface, delivering a professional finished appearance without additional prep work\u003c\/li\u003e\n\u003cli\u003eDeep T40, 6-lobe recess - provides a secure, cam-out-resistant drive engagement so the fastener seats consistently and reliably, with the drive bit included in packaging\u003c\/li\u003e\n\u003cli\u003eHeavy-duty shank - adds strength and durability to each connection, supporting high load capacity across structural wood framing applications\u003c\/li\u003e\n\u003cli\u003eShank knurl - reduces driving torque so installers can work more efficiently with less effort and tool wear\u003c\/li\u003e\n\u003cli\u003eType-17 point - self-starts quickly and reduces installation torque, eliminating the need for predrilling in most applications and speeding up installation\u003c\/li\u003e\n\u003cli\u003ePartially threaded design - concentrates clamping force between structural members, drawing them together tightly for a strong, lasting connection\u003c\/li\u003e\n\u003cli\u003e8 mm x 80 mm (3 1\/8 in.) length - sized for structural mass timber, modular construction, timber framing, and multi-ply engineered wood fastening\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 - this screw addresses the unique demands of cross-laminated timber and structural composite lumber assemblies where holding power, flush installation, and embrittlement resistance all matter\u003c\/li\u003e\n\u003cli\u003eNo predrilling required in most applications - the Type-17 point and low-friction e-coat finish combine to reduce installation time and labor cost on general framing, post frame, and timber framing projects\u003c\/li\u003e\n\u003cli\u003eCSA O86:24 compliant hardness profile - gives builders and engineers confidence that this fastener meets recognized standards for hydrogen embrittlement mitigation, reducing the risk of brittle fracture in structural connections\u003c\/li\u003e\n\u003cli\u003eFriction-reducing e-coat finish - lowers driving torque compared to uncoated alternatives, helping installers drive more fasteners per charge in modular, factory-built, and engineered wood applications\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\u003eLength:\u003c\/strong\u003e 3 1\/8 in.
