Cortex Concealed Fastening System for Timber Tech Decking is a fast and easy way to conceal fasteners and screw heads when installing Timber Tech decking boards. The Fasten Master Cortex box includes everything needed, including 224 screws, 300 plugs and 2 setting tools. Fasten-Master recommends installing with an 18 volt cordless impact drill.
How many fasteners are needed? Horizontal trim boards less than 12" wide, use two Cortex fasteners at every framing member-rafter tail or wall stud. The screws should be 16" OC or closer. Vertical trim boards (i.e., next to a door or a window), use two Cortex fasteners every 16" OC or closer. If a trim board is 12" or wider, use three screws. Each trim board must be fastened within two inches of the end of each board.
Note: Predrilling is not required throughout the majority of the project. Predrilling is required when fastening within 1/2" of the end of a board and at mitered joints. Use a 3/16" drill bit for predrilled pilot holes.
