TimberTech Cortex Ashwood Hidden Fasteners for PRO and EDGE, 100 Ln. the strongest hidden fastener system from TimberTech, designed to provide an ultra-clean and high-quality appearance for your decking projects. These fasteners come with color-matched plugs that blend seamlessly with your deck’s Ashwood finish. Featuring a specialty ACQ- deck screw with a TORX ttap drive system, they deliver exceptional strength and durability. Unlike other hidden fastener systems, Cortex fasteners can be used across the entire deck surface, including stairs and perimeters, ensuring a consistent look throughout. They are compatible with all full-profile TimberTech deck boards except for scalloped boards from the Terrain, Prime, Prime+, and Reliaboard collections. Installation requires predrilling with a 7/32” drill bit to pilot a hole halfway through the deck board without penetrating the framing. Please note that Cortex for PRO EDGE is not compatible with metal framing; for steel framing, separate Cortex Drillers from FastenMaster must be used. This pack covers 100 linear feet and includes 224 carbon steel screws and 300 plugs, making it a complete solution for your decking needs. Model Number: CTX100LCAW
