Cortex Hidden Fastening System for Decking

The Cortex Hidden Fastening System is the fastest, easiest way to hide fasteners in composite, capstock, and PVC decking boards.

Cortex offers a strong connection between the deck board and joist. It hides fasteners across the entire deck, first and last board, perimeter and stairs. And it just got better!

Cortex now comes with the following product enhancements:

  • TORX® ttap® Drive System: This system is almost impossible to strip-out. In addition, the stability button keeps the fastener straight through installation.
  • Modified Fastener: New thread design reduces installation torque and dramatically increases fastener strength. Length moves from 2 ½”.
  • Stronger Setting Tool: 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.
