Cortex Hidden Fasteners

Cortex Hidden Fastening System for Azek, Timbertech, and Trex Decking. This innovative system hides the heads of your deck screws with color-matched plugs. Cortex Hidden Fasteners have been redesigned with a new thread design requiring less torque, and a new bit made from stronger material for extreme pro contractor use that uses the Torx TTAP head. The TTAP head makes it almost impossible to strip the fasteners, allowing for easy removal, and a stability button keeps the screw straight when drilling.

The Cortex Fasteners, or Cortex Driller, for Trex Elevations do not have the TTAP head, they still use the square drive bit.
