DeckWise® Composite Deck Screws - #10 x 2-3/4" - 100 ct
DeckWise® Composite Deck Screws are specifically engineered for composite, PVC, and capstock decking materials. The unique fluted head design reduces unsightly "mushrooming"—the raised material that occurs when standard screws are driven into composites. Reverse threads under the head pull material snug to the joist framework for a crisp, professional finish without pre-drilling. 316 grade stainless steel with anti-fade painted heads that match popular composite deck colors. T20 star drive prevents stripping. Available in Hardwood Brown, Outdoor Grey, and Redwood to match Trex, TimberTech, Fiberon, and other composite brands.

About this product
These 305-grade stainless steel fasteners are specifically engineered to eliminate the 'mushrooming' effect common in composite and PVC decking materials while providing the corrosion resistance necessary for outdoor environments. Featuring a color-matched cap head and a dual-thread design, they ensure a clean, flush finish for deck boards, trim, and fascia. This 100-count pack is ideal for small projects, repairs, or detail work where aesthetics and durability are paramount.

Best used for
- 1Installing composite or PVC fascia and trim boards to complement tropical hardwood decks like Ipe or Cumaru.
- 2Securing perimeter boards on rooftop decks where stainless steel fasteners are required for long-term weather exposure.
- 3Detailing deck stairs and handrails where color-matching the fastener head to the deck surface is preferred for a hidden look.
- 4Fastening high-density trim boards in coastal applications where standard galvanized screws would fail due to salt spray.
Pro tips for dense hardwoods
- Always pre-drill pilot holes when using these screws near the ends of boards to prevent splitting, even with the self-tapping Auger point.
- For the best aesthetic results in dense materials, use a countersink tool to ensure the cap head sits perfectly flush with the surface.
- Set your drill's clutch to a medium-low setting to prevent over-driving the head, which can compromise the fastener's holding power and appearance.
- Maintain consistent spacing between boards using spacers to allow for natural expansion and contraction of the deck surface.

Why Choose Screws & Fasteners?
How to Face-Screw Hardwood Decking
Pre-Drill Every Hole
Dense hardwoods (1,500+ Janka) will split without a pilot hole. Use a countersink bit sized for your screw shank — this is non-negotiable for Ipe, Cumaru, and similar species.
Choose Stainless Steel
Carbon steel screws corrode and stain hardwood within months. Always use Type 316 stainless steel — it offers the best corrosion resistance for exotic hardwoods and coastal environments. The slight premium pays for itself in zero staining and no fastener failures.
Drive to Depth — Not Beyond
Set screws flush with the surface or just barely countersunk. Over-driving creates water-collecting craters that accelerate checking around each hole.
Two Screws Per Joist Crossing
Place one screw roughly 1″ from each board edge at every joist. This prevents cupping and ensures the board stays flat over time.
Pro Tip from Our Deck Specialists
Apply a drop of wax or soap to each screw tip before driving — it dramatically reduces friction and prevents snapped screw heads in ultra-dense wood like Ipe.
