Composite Deck Screws, 316 Stainless Steel, #10 x 2-1/2", 100PCS - for PVC & Composite Decking, Flush Finish Cap Head, Reverse Thread, T20 Star Drive, Bit Included, Natural

Composite Deck Screws – 316 Stainless Steel for PVC & Composite Decking Engineered for durability and clean results, these composite deck screws are designed specifically for face-fastening PVC and composite deck boards, including capped composite surfaces. Ideal for a wide range of outdoor applications such as deck boards, fascia, stairs, railings, docks, boardwalks, and pool decks, each screw delivers consistent performance across all project types. Available in multiple sizes, colors, and pack quantities, this versatile solution ensures you can match the right fastener to your exact build requirements. Crafted from 316 marine-grade stainless steel, these screws provide superior corrosion resistance in coastal environments, high-humidity regions, and wet conditions. This premium material ensures long-lasting strength and reliability, helping maintain the integrity and appearance of your decking over time without rust or staining concerns. The T20 star drive system features an extra-deep recess to reduce cam-out and improve driving stability, allowing for better control and efficient installation. Each package includes a compatible driver bit, so you’re ready to start your project immediately with the proper fit and reduced tool wear. Designed with a flush finish cap head, these screws sit smoothly on the deck surface for a clean, professional appearance. Integrated reverse upper threads help minimize surface bulging, often referred to as “mushrooming,” resulting in a more refined and uniform finish across boards. Advanced thread and tip features enhance performance during installation. The tri-lobe shank increases grip while reducing driving resistance, while the Type 17 cutting point enables fast starts with less splitting. Dual cutting grooves help clear material efficiently for smoother penetration. For best results, a pilot hole is recommended when working near edges or with dense framing materials. Built for both professionals and DIY users, these composite deck screws deliver reliable fastening, clean aesthetics, and long-term outdoor performance across all available size, color, and quantity variations.
