The Simpson Deck-Drive DCU Screw Plug in Azek Slate Gray is a finish-grade PVC plug solution from Simpson engineered to eliminate visible screw heads when fastening composite deck boards and PVC trim. Each plug is manufactured directly from Azek Deck material, producing an exact color and texture match in Slate Gray that blends seamlessly into the deck surface for a clean, professional result. Sold in a 375-plug package, this product is a key component of the Deck-Drive DCU hidden fastening system and is designed for use exclusively with Simpson Strong-Tie Deck-Drive DCU Composite screws alongside the Auto-Set Driver bit, each sold separately.

Key Features

• Manufactured from Azek Deck material for an exact color and texture match - plugs blend into the deck surface so screw locations become virtually invisible, preserving the finished look of your project.
• Conceals screw head completely - eliminates exposed fastener hardware that can detract from the appearance of composite decking and PVC trim installations.
• Tapered design for easy insertion - the tapered profile guides each plug into the countersunk hole quickly and securely, reducing installation effort.
• Made from PVC decking material - shares the same weathering resistance as the deck boards themselves, so color and texture hold up in outdoor environments over time.
• Compatible exclusively with Simpson Strong-Tie Deck-Drive DCU Composite screws - ensures a precise fit and a consistently flush, professional finish when used as part of the complete DCU fastening system.

Why This Product

• A seamless, matched finish every time - because these plugs are made directly from Azek Deck material, the color and texture match is exact rather than approximate, giving composite deck surfaces and PVC trim a polished look with no visible fasteners.
• Built to handle outdoor exposure - PVC construction means the plugs resist weathering the same way the surrounding deck boards do, maintaining their appearance without the cracking, fading, or shrinkage concerns associated with wood plugs.
• A complete system approach - these plugs are purpose-built to work within the Deck-Drive DCU hidden fastening system, so contractors and DIYers get a coordinated solution rather than mismatched components.
• Broad finish application coverage - with 375 plugs per package and approved use across composite deck boards, PVC trim, and fascia applications, this quantity is well suited for full deck builds and large finishing projects.
