The FastenMaster Cortex Hidden Fastening System is the fastest, easiest way to hide fasteners in composite, cap stock, 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.Cortex plugs are made with the same material as leading deck boards, meaning you can achieve a perfect seamless finish across your whole deck. Once installed, Cortex plugs become a part of your deck, expanding and contracting along with the boards around them - this means your plugs will not need to be replaced for the lifetime of the project. Featuring a TORX ttap drive system and a high-strength setting tool - Cortex screws are easy to install and optimized for use by the PRO contractor.To install, simply drive the Cortex fastener using the included setting tool - this will countersink the screw to the perfect depth. Then, place your Cortex plugs on top of the fastener holes with the grains aligned, and tap to finish.Designed to fasten 50 lineal feet of Fiberon ArmorGuard Brazilian Walnut decking. Includes 75, 2-1/2 inch carbon steel Cortex decking screws, 100 Cortex plugs and 1 Cortex setting tool.A winner of the 2022 Home Depot Innovation Award, Cortex is trusted by PROs everywhere who are dedicated to craftsmanship and quality.

The Cortex Fastening System for Veranda Trim includes 75 screws, 80 collated plugs and 1 setting tool.
This specific Cortex product is for Azek trim. Fasten Master makes a Cortex system specifically for the Trex fascia board 1"x12"x12" (which is really .56" thick). The Cortex for Trex fascia screws and plugs are different than the ones for Azek. It is available in all the Trex fascia colors. Please ask your local Home Depot associate or contact Fasten Master at 800-518-3569 if you have any further questions.
Thank you for pointing out this inaccuracy. This appears to be an error on the website and we are working to have this corrected. Our Cortex kits are made from the deck or trim boards themselves, so the plugs are an exact match and will wear and weather the same. The color "tan" would be an exact match for that specific trim board. Please give us a call at 800-518-3569 and ask for Customer Service, if you should have any additional questions.
Yes, the Azek Trim collections are exterior screws.
The minimum thickness for the Cortex is 5/8" so this would be too thin. In some cases we have a Cortex Fascia kit designed for thinner fascia materials. It comes with a boring tool, wider headed screw and plug. Unfortunately, this is not available in Veranda.
Please contact us if you have run out of plugs. We will gladly send you more plugs at no charge with a proof of purchase for this product. Reach out to us at 800-518-3569.
Thank you for your question. The above plugs are smooth.
