The Simpson Deck-Drive DCU Screw Plug in Azek Coastline from Simpson Strong-Tie is a PVC plug engineered to conceal screw heads on composite and PVC deck boards, delivering a clean, professional finish that lets the natural look of your outdoor space take center stage. Each plug is manufactured directly from Azek Deck material, ensuring an exact color and texture match to Azek Coastline boards along with the same resistance to weathering as the surrounding deck surface. Designed as part of the complete Deck-Drive DCU Hidden Deck-Fastening System, these plugs work together with Simpson Strong-Tie Deck-Drive DCU Composite screws and the Auto-Set Driver bit - each sold separately - to eliminate visible fasteners and achieve a seamless, polished result across decking, trim, and fascia applications.

Key Features

• Manufactured from Azek Deck material for an exact color and texture match - blends invisibly with Azek Coastline boards so no plug stands out against the surrounding deck surface.
• Built-in resistance to weathering - because the plugs are made from the same PVC decking material as the boards themselves, they hold up to outdoor exposure at the same rate as the deck, keeping the finished surface looking consistent over time.
• Conceals screw heads completely - eliminates visible fasteners for a smooth, uninterrupted deck surface that enhances the overall appearance of the project.
• Tapered design for easy insertion - the tapered profile guides each plug into the screw hole cleanly and accurately, reducing installation effort and the risk of misalignment.
• Compatible exclusively with Simpson Strong-Tie Deck-Drive DCU Composite screws - ensures a precise fit and flush finish when used as part of the intended fastening system, protecting the integrity of the completed deck surface.
• Requires the Auto-Set Driver bit for installation (sold separately) - using the correct driver bit guarantees consistent seating depth across every plug, producing a uniform, professional appearance throughout the entire project.

Why This Product

• A true material match, not just a color approximation - because these plugs are manufactured from Azek Deck material itself, they replicate the exact color, texture, and weathering characteristics of Azek Coastline boards, something a generic plug cannot replicate.
• Purpose-built for a complete hidden fastening system - designed specifically to work within the Deck-Drive DCU system alongside Simpson Strong-Tie DCU Composite screws and the Auto-Set Driver bit, every component is engineered to work together for a predictable, professional result.
• Eliminates the visual distraction of exposed screw heads - ideal for homeowners and contractors who want composite deck boards, PVC trim, and fascia installations to look finished and cohesive rather than hardware-heavy.
• Generous pack quantity supports meaningful project coverage - the 375-plug pack is sized to cover approximately 100 square feet of deck surface, making it practical for real deck projects without requiring frequent reordering mid-job.
