FastenMaster's Collated Cortex Hidden Fastening System creates a smooth, unblemished decking surface by hiding your fasteners. Each plug is made from the exact same PVC material as your TimberTech AZEK Vintage, TimberTech AZEK Landmark or TimberTech AZEK Harvest deck boards for a perfect color and texture match.

Just countersink your screw below the surface and insert the color-matching plug to fill the gap and completely hide your fastener. These Collated Cortex Replacement Plugs come in packs of 40. To sink your screws to the perfect depth, order plugs along with steel screws and FastenMaster's screw-setting tools in our Collated Cortex Hidden Fastening System for TimberTech AZEK Decking.

Collated Cortex Replacement Plugs are available in the TimberTech AZEK Vintage finishes of Coastline, Dark Hickory, English Walnut, Mahogany, and Weathered Teak, the TimberTech AZEK Landmark finishes of American Walnut, Castle Gate, and French White Oak, and the TimberTech AZEK Harvest finishes of Brownstone, Kona, and Slate Gray.
