Product Description
Simpson Strong-Drive SDCP TIMBER-CP Screw - 10 mm x 100 mm, Black E-Coat by Simpson Strong-Tie is a structural wood fastener engineered for cross-laminated timber (CLT), mass timber construction, and general interior wood-to-wood fastening. This partially threaded screw is built to pull structural members together with superb holding power, combining a flat head with underhead nibs for clean, flush countersinking and a Type-17 point that starts fast and drives without predrilling in most applications. The black e-coat electrocoating finish is a construction-durable, nonmetallic, friction-reducing surface treatment that supports use with FRT lumber and meets ICC-ES AC257 Exposure Condition 3 requirements - making it a reliable choice for interior and dry-service structural assemblies.
Key Features
- Black e-coat electrocoating finish - provides a construction-durable, nonmetallic and friction-reducing coating approved for FRT lumber and corrosion resistance (ICC-ES AC257 Exposure Condition 3), so installers can use this fastener with treated interior lumber without compromising finish integrity
- Optimized hardness profile compliant with CSA O86:24 - mitigates external hydrogen embrittlement issues, reducing the risk of brittle fracture in demanding structural timber applications
- Flat head with underhead nibs - helps countersink cleanly and flush with the surface for a neat, professional finish without additional preparation
- Deep T40, 6-lobe recess - delivers a secure, high-torque drive connection that reduces cam-out and improves control, with a driver bit included for immediate use
- Heavy-duty shank - provides the strength and durability needed for structural timber fastening under load
- Shank knurl - aids in torque reduction during installation, lowering driver strain and improving drive efficiency
- Type-17 point - ensures fast starts, reduces installation torque, and eliminates the need for predrilling in most applications, speeding up assembly
- Partially threaded design - pulls structural members together with excellent clamping force and load capacity suitable for engineered wood and mass timber connections
Why This Product
- Purpose-built for mass timber and CLT construction - this screw is specifically designed for cross-laminated timber, structural composite lumber, and engineered wood fastening where holding power and compliance with timber design standards like CSA O86:24 are required
- Low-friction coating means less torque and faster drives - the black e-coat finish reduces friction during installation, so installers can drive these screws with less effort and without compromising structural performance
- No predrilling required in most applications - the Type-17 point and shank knurl work together to minimize installation steps, saving time on general framing, timber framing, post frame, and modular construction projects
- Interior and FRT lumber compatible - the e-coat finish is approved for use with fire-retardant-treated lumber in interior and dry-service environments, expanding the range of appropriate structural applications without requiring a separate specialty fastener
