Deck Fasteners in Action



Whether out of sight or on the surface, Fiberon deck fasteners get the job done.

Choose Phantom hidden fasteners for a smooth, uninterrupted deck surface or Cortex face fasteners with color-matched plugs that blend seamlessly with the color of your deck. Both fastener systems provide superior holding power, and are corrosion-resistant for a durable, long-lasting finish that is sure to give you a look you'll love.

    Fiberon Cortex Screws

For a traditional face-fastened look, choose Fiberon Cortex screws – the only hidden face fasteners approved for Fiberon decking. Easy to install, Cortex screws work with a special driving tip that automatically places the screw at the precise depth. Then, a color-matched plug is tapped in to minimize the appearance of hardware. So you get a cleaner, more attractive decking surface.

  • FAQs
    Can Fiberon Phantom Hidden Deck Fasteners be used with decking other than Fiberon?

    Phantom Fasteners are for use with most composite decking products. Non-grooved composite decking boards can be grooved** with a slot cutting bit to accommodate the Phantom Fastener. Recommended bits are:

    • UFO, PN: The Groover
    • Woodstock International, PN: DC1098
    • Bosch, PN: 85530M
    • Sears, PN: SPM215190769
    • Sears, PN: SPM215190779
    • Grizzly Industrial, PN: C1098

    **Cutting grooves or slots into deck boards may void the manufacturer's warranty. Fiberon does not warrant or guarantee your warranty will remain valid.

    Can I use hidden fasteners on Paramount decking?

    Paramount Decking is available in both square edge and grooved deck boards. The following are approved fastening systems for Paramount Decking, a capped cellular PVC deck board.

    Hidden Face Fastening and Face Fastening Installations – Square Edge Boards

    Fiberon Cortex Screws are the only approved hidden face fasteners recommended for Paramount decking. Fiberon Cortex screws are available in all colors of Paramount Decking. For non-hidden face fastener installations, approved surface fastening is accomplished with a minimum #8 x 2 ½” composite deck screw with an ACQ corrosion-resistant coating or stainless steel. For all face fastening installations, install perpendicular to the deck surface, not at an angle. Position screws no closer than 1/2" from board edges or board ends, using two screws in every joist.

    Hidden Fastening Installations – Grooved Boards

    Fiberon recommends the Tiger Claw TC-G® hidden fastener in combination with Fiberon Cortex Fasteners as the only approved system for installing hidden fasteners in grooved Fiberon Paramount deck boards.

    Tiger Claw TC-G Hidden Fasteners

    The TC-G side hidden fastener installed with an impact-driver creates a tighter connection to the joist, alleviating potential sound caused by the boards moving against the joist. Maximum residential joist spacing is 16” on-center for perpendicular-to-joist applications. With all side hidden fasteners, use a minimum of one Cortex surface hidden fastener positioned in the center of each board to mitigate potential sound and to ensure the boards stay positioned during normal thermal expansion and contraction of the deck boards.

    Other Considerations

    • Spacing the deck joists at 12’” on-center will increase stiffness and mitigate sound potential. Maximum residential joist spacing is 16” on-center for perpendicular-to-joist applications.
    • Self-adhesive Joist Tape: Regardless of the method of fastening, using self-adhesive joist tape will help reduce potential sound caused by boards moving against the joist, and is designed to protect the joists from premature weather-related deterioration.

    See the technical bulletin for installation instructions for Paramount grooved decking.

    What type of surface fasteners are recommended for Good Life Decking?

    We recommend 2.5-inch #8 or #10 stainless steel or composite screws for surface-fastening Good Life Decking. Do not use Cortex fasteners, or any other fastener with a plug. Here’s why: Good Life Decking has a scalloped bottom. The scallops are located on the underside of where you would insert the screw. Because those areas are naturally thinner, the screw does not have sufficient material to grab. This results in a less secure installation and a far greater risk of cracking over time due to pressure/vibrations.

    Can I install Fiberon decking with another manufacturer’s hidden deck fasteners?

    Only Fiberon Phantom hidden deck fasteners are recommended for use when installing Fiberon decking. (Note: hidden fasteners will only work with grooved edge boards, not square end boards.) Using another manufacturer’s product will void your warranty, and may result in an unsatisfactory installation. Trex Universal Clips, for example, do not hold the boards securely during thermal expansion and contraction caused by temperature swings. Consequently, you could experience significant end-gapping issues.

    Always read and follow Fiberon decking installation instructions to ensure correct installation and keep your warranty coverage intact.
