Product Description
The Simpson Deck-Drive DCU Composite Screw #10 x 2-3/4 in. 316 Stainless Collated is an engineered fastener purpose-built for composite and PVC decking installations where a clean finish, reliable seating, and long-term corrosion resistance are non-negotiable. Designed by Simpson to eliminate the need to mix and match screws across different composite decking products, this collated screw delivers consistently professional results whether you are working with Trex or other popular composite deck boards. The curved collation format pairs directly with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system, keeping crews productive across large deck projects without sacrificing finish quality.
Key Features
- Tri-lobe thread design - reduces stress and damage to composite board material during driving, preserving the structural integrity and appearance of the deck surface
- Inverted upper threads - clear excess material away as the screw seats, ensuring a consistent, flush installation every time without manual cleanup
- Type-17 point - penetrates composite decking quickly for faster starts, reducing drive time and minimizing the effort required on each fastener
- Cap head geometry - prevents mushrooming and stops material from rising above the deck surface, producing a smooth, professional-looking finish across the entire deck
- Type 316 stainless steel construction - provides severe-level corrosion resistance, making these screws well-suited for harsh outdoor environments with heavy moisture exposure
- T20 6-lobe drive - delivers positive bit engagement and reduces cam-out during installation; a compatible driver bit is included in the package
- Trex-approved fastener - meets Trex composite decking approval requirements, giving contractors and homeowners confidence in code-compliant installations
- Curved collation format - compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system, enabling faster, more ergonomic installation on large composite deck projects
Why This Product
- One screw for all composite decking types - the Deck-Drive DCU is engineered to work across all types of composite and PVC decking, eliminating the hassle and risk of selecting the wrong fastener for a specific board brand or product line
- Finish quality built into the design - the combination of the cap head, inverted upper threads, and tri-lobe thread pattern work together to prevent mushrooming, clear debris, and seat the screw consistently flush, reducing touch-up work and delivering a cleaner finished deck
- Severe-environment corrosion resistance - Type 316 stainless steel goes beyond standard stainless grades, making this screw a reliable long-term choice for coastal, waterfront, and other high-moisture outdoor decking applications
- Auto-feed system compatibility for high-volume installs - the curved collation design works directly with the Simpson Strong-Tie Quik Drive PRO300SG2, allowing crews to drive screws faster and more consistently across large decking projects without bending over for each fastener
