The fastest, easiest way to hide the heads of your fasteners in your PVC Trim just got better!
Cortex now comes with the following product enhancements:
Shorter Trim Fastener: A new 2” fastener will replace the 2-3/4”. This new length delivers high levels of holding power but now offers versatility for applications such as Deck Fascia and Exterior Baseboards.
Faster Trim Screw Design: The dual lead thread design spins the fastener 50% faster for quicker installs.
TORX® ttap® Drive System: This system is almost impossible to strip out and the fastener is easily removed. In addition, the stability button keeps the fastener straight through installation.
Stronger Setting Tool: The Setting Tool has been optimized for extreme pro contractor use. Stronger bit material and industrial grade felt will enable you to install 350 fasteners on one Cortex Setting Tool.
No more caulking, sanding or painting needed! Each package comes complete with screws, plugs, and setting tools in a 50, 250 or 750 lin ft box.

Trim Board Dimensions
The FastenMaster Cortex Hidden Fastening System is designed for use with PVC Trim with actual thicknesses of 5/8" to 5/4".
General Fastening Guidelines
For 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" on center or closer. If you are attaching a vertical trim board (i.e., next to a door or a window) use two Cortex fasteners every 16" on center or closer.
If trim board is 12" or wider, use three screws. Each trim board must be fastened within two inches of the end of each board.
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.
Setting the Cortex Fastener
Use a cordless impact driver and the Cortex setting tool. Drive the Cortex fastener to the preset level below the PVC Trim surface. The Cortex screw must be driven perpendicular to the trim surface.
Cortex Tip: To remove a Cortex screw set below the trim surface, replace the Cortex setting tool in your impact driver with a #1 square drive bit. This allows full access to the seated screw.
Setting the Cortex Engineered Plug
To ensure a strong bond, the cored hole must be free of dirt or rain water.
Using Other Screws and Plugs
The Cortex System is designed to offer ultimate long term performance. The interaction between the PVC Trim, fastener and plug is essential. The Cortex connection is fully tested and warranted. Use of non-Cortex screw or non-Cortex plug will result in nullifying the FastenMaster warranty.
