Product Description
Simpson Strong-Drive SDCP TIMBER-CP Screw - 10 mm x 320 mm, Black E-Coat by Simpson Strong-Tie is a heavy-duty structural fastener engineered for cross-laminated timber (CLT), mass timber construction, and a wide range of general interior wood framing applications. The black e-coat electrocoating finish delivers a construction-durable, low-friction, nonmetallic surface that reduces driving torque and provides corrosion resistance suitable for interior and dry-service environments. Whether you are fastening engineered wood assemblies, working in factory-built or modular construction, or tackling structural wood-to-wood connections, this partially threaded screw pulls members together with superb holding power and excellent load capacity.
Key Features
- Black e-coat electrocoating finish - provides a construction-durable, nonmetallic, friction-reducing coating approved for ICC-ES AC257 Exposure Condition 3, making it suitable for fire-retardant treated (FRT) lumber and corrosion-sensitive interior applications
- Optimized hardness profile compliant with CSA O86:24 - mitigates external hydrogen embrittlement risk, giving you a structurally reliable fastener for mass timber and CLT projects where brittle fracture is a concern
- Flat head with underhead nibs - enables clean, flush countersinking without surface tear-out, delivering a professional finish on exposed timber surfaces
- Deep T40, 6-lobe recess - provides a secure, cam-out-resistant drive for consistent installation, and includes a driver bit so you can start work immediately
- Heavy-duty shank with shank knurl - combines strength and durability with reduced torque during installation, minimizing driver wear and installer fatigue
- Type-17 point - ensures fast starts and reduces installation torque, eliminating the need for predrilling in most applications and speeding up workflow on the job site
- 10 mm diameter x 320 mm length (12 1/2 in.) with a 3 1/8 in. thread length - partially threaded design pulls structural members tightly together for superior clamping action in timber-to-timber connections
Why This Product
- Purpose-built for mass timber and CLT construction - the optimized hardness profile and CSA O86:24 compliance address hydrogen embrittlement concerns specific to large-section structural wood assemblies, making this screw the right choice for demanding mass timber projects
- Low-friction black e-coat reduces driving torque - the electrocoating allows these large-diameter fasteners to be driven with less effort compared to uncoated alternatives, improving productivity in high-volume framing applications
- No predrilling required in most applications - the Type-17 point and shank knurl work together to reduce installation time and eliminate an extra step, keeping structural wood framing and engineered wood assembly projects on schedule
- Corrosion resistance approved for ICC-ES AC257 Exposure Condition 3 - the black e-coat finish is specifically approved for use with FRT lumber, addressing a common compatibility challenge in interior structural applications where treated lumber is specified
