Cortex for Azek Trim by FastenMaster

The Cortex Hidden Fastening System for PVC Trim is the fastest, easiest way to hide fasteners in PVC Trim - and now it is 50% faster.

Cortex now comes with the following product enhancements:

  • Collated Cortex Plugs: FastenMaster Cortex plugs are now available on a collated strip. This minimizes handling and saves valuable time on the job site.
  • Shorter & Faster Trim Screw: A new 2” fastener option delivers high levels of holding power but now offers versatility for applications such as deck fascia and exterior baseboards. 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. The stability button keeps the fastener straight through installation.
