So you get a cleaner, more attractive decking surface.
  • Color-matched plug made from fiberon decking minimizes the appearance of hardware
  • Installed on the boards surface
  • Use with square edge or grooved edge boards
  • Special driving tip automatically puts the cortex screw at a precise depth, then the color-matched plug is tapped in with a hammer

Can these be used with the ArmorGuard 15/16 in. x 5-1/4 in. x 8 ft. Nantucket Gray Square Edge Ca...

Asked by Mich May 10, 2021

Answer

Thank you for your question. We do not recommend the Cortex fasteners, or anything like the Cortex fasteners with plugs, for the ArmorGuard decking material due to the arches in the bottoms of the boards. The screws will be inserted where there is an arch, and recessing of the screw for the plug can cause immediate or eventual cracking of the material.

Answer

the screw and plug system is design to only match the exact color and board. Each plug is punched from the exact board. If your board has been discontinued we would not recommend nor sell the screw and plug for this discontinued color cottage gray. Pebble Gray is the screw which matches best.

Thank you for your question today. Cortex plugs are made from each specific board. Therefore, Castle Grey Cortex is only recommended and warrantied to be used with Fiberon Horizon Castle Grey decking. At this time, we do not make Cortex for Gladiator baseboards.

will these work with the Nantucket Gray

Asked by JoeA May 16, 2020
1
Answer

Thank you for your question. We do not recommend the use of any screw and plug system with the ArmorGuard decking due to the channels in the bottom of the board. Recessing a screw for a plug in a channel location could lead to cracking of the deck board, so only standard composite deck screws should be used that would be installed flush with the surface and visible.

Do these work for seaside gray?

Asked by Justin23 May 13, 2020
1
Answer

Thank you for your question. These are not the same color as the Seaside Grey, and we do not recommend the use of any plug system with the ArmorGuard decking. Recessing the screws deep enough to accommodate the plugs can crack the board in the channels. Standard composite deck screws installed flush with the surface are the only approved fasteners for square edge boards.

Will this color work with Veranda gray composite decking?

They will probably work, but may have a slight color variation, but even castle gray plugs have a slight color variation with castle gray decking.

Thank you for your review and we are happy the Cortex screws were able to help with your project and still have a fastener free appearance. FiberonHomeDepot

On the surface, this system looks and installs great. The problem will surface 6 years later, when the screws literally disintegrate. I put down an entire back deck with these fasteners, and now they are literally rotting away. And the ones that rusted to a pulp didn’t even get wet. They need to be made from stainless steel, or something along those lines.

Thank you for your review and we are sorry if you experienced an issue with the Cortex screws. Fiberon did not offer these screws for our decking 6 years ago, but we appreciate the feedback provided and ask that you contact FastenMaster at 800-518-3569 so they may investigate your concerns with the performance of the screws.
