Cortex Screws for Fiberon

Cortex Hidden Fastening System for Fiberon 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. Covers 100 Linear Feet. Includes 224 Screws, 300 Plugs, Plug Bit, and TTAP Screw Bit.

  1. wish it was made with stronger material so it doesn't strip. review by MK on 5/15/2019
    Overall Product Rating

    Shipping & delivery great. no issues there. The screws are good for one time only. If the first time it does't go down completely you can not un-screw it and bring out to try again. The head strips in no time. I had to cut the head off on several screws. I wish they were made with better materials.

  2. Great Product! review by Jason on 9/10/2018

    I purchased these for a Fiberon deck that I built and they worked perfectly. The color matching plugs are not able to be seen once inserted into the screw holes.
