TimberTech® is focused on fasteners. Opt for the best fastening systems to install your deck. These high-quality fasteners give decks added strength and integrity for years to come. Square-shoulder boards allow for top-down fastening, while grooved boards are designed for hidden clip fasteners. TOPLoc® color-matched deck fasteners are installed from the top down directly into capped composite deck boards in the TimberTech® Composite decking lines. These fasteners are made of high-quality, coated carbon steel 2½ in. screws to provide a fast and easy installation. Refer to the overview section and open the Fastening Guide to find the correct color-matched fasteners for your deck.
