FastenMaster Cortex for Trex Fascia: Premium Hidden Fastening System

Achieve a flawless, screw-free look for your deck with FastenMaster Cortex for Trex Fascia. This specialized hidden fastening system combines the structural strength of a face-driven screw with the high-end aesthetics of a hidden fastener. By using color-matched plugs made from actual Trex material, the system completely conceals screw heads, ensuring a seamless and professional finish for your fascia boards.

✨ Key Features

🛡️ True Hidden Aesthetics

Cortex offers unmatched concealment. The included plugs are color-synced to blend perfectly with your TREX fascia & riser boards, making the fastening points virtually invisible to the naked eye.

🔧 Durable & Weather-Resistant

Engineered by FastenMaster for maximum longevity, these fasteners are built to withstand the elements. They resist corrosion and prevent the warping or movement of fascia boards, keeping your deck's perimeter tight and secure for decades.

⚡ Fast, One-Step Installation

The system is designed for efficiency. Using the included setting tool, you can drive the screw to the exact depth required in one motion, leaving a perfect hole for the plug.
