Description

Cortex Concealed Fastening System for Trex Decking is a fast and easy way to conceal fasteners and screw heads when installing Trex decking boards. The FastenMaster Cortex box includes everything needed, including 224 screws, 300 plugs and 2 setting tools. FastenMaster 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.
