About This Product

The FastenMaster Collated Cortex Hidden Fastening System for PVC Trim is the fastest, easiest way to hide trim fasteners in PVC Trim. Features TORX ttap Drive System which is almost impossible to strip-out and the deck fastener is easily removed. The stability button keeps the fastener straight through installation. Cortex plugs are made with the same material as leading trim boards, meaning you can achieve a perfect seamless finish every time. Once installed, Cortex plugs become a part of your trim board, 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. The plugs come pre-aligned on a collated strip, eliminating the need to fumble around with loose plugs and making installation 50% faster. 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 250 lineal feet of AZEK Traditional Trim. Includes 375, 2 inch carbon steel Cortex trim screws, 400 collated Cortex plugs and 3 Cortex setting tools. Cortex is trusted by PROs everywhere who are dedicated to craftsmanship and quality.

    A:  The plugs are made from the actual boards they are packaged for. We do not recommend mixing and matching. Please call Fastenmaster at 1-800-518-3569 and ask for Customer Service. We will be glad to help you with the appropriate package for the trim you are using.

      Overall, average rating. A majority of the plugs had become dislodged from the plastic strip, so it was a pain to install them. The felt piece of the bit fell off about 1/2 way through. For the price, this system is over priced, but there aren’t many options.
      Response from FastenMaster teamSep 20, 2023
      Thank you for reaching out. I'm sorry about the felt coming off the bit and the trouble you had with the strips of plugs. I believe there are several bits in the box. If not, I can send you a pack of bits if you provide you name and address. fastenmaster
        Nice for exterior work that you are not painting and can’t cover with trim. Overpriced and you can do better with SS nails, trim, caulk and paint. If you are painting just skip this.
        Response from FastenMaster teamJul 26, 2023
        Thank you for taking the time to review our product. The Cortex for trim is designed to eliminate having to do all those extra steps of having visible screws or nails, waiting for caulking to dry before painting. With this system you just drive the screws in, insert the plug and you're done. The plugs are cut from the same board so you don't have to worry about plugs and board weathering at different colors, typically seen with caulking. Please feel free to contact Fasten Master @ 800-518-3569 if you have any questions. fastenmaster
