Description

The FastenMaster Cortex for Boral Trim - 50 Linear Feet is a fast and easy way to conceal fasteners and screw heads when installing PVC trim Boards. Cortex is easy-to-use and includes everything needed, including (75) screws, (100) plugs, and a setting tool. FastenMaster recommends installing with an 18 volt cordless impact drill. The Cortex for Trim Fastening System is designed for use with PVC Trim with an actual thickness of 5/8" to 5/4".

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.
