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.
When you want a smooth deck surface and a seamless transition from the indoor to the outdoors, choose Fiberon Phantom GT and Phantom EC (End Clip) Hidden Fasteners.
Fiberon Phantom 20EC (End Clip) Fasteners offer the same superior holding power as the rest of the Phantom Hidden Fasteners collection. They are designed specifically for use with Paramount PVC perimeter boards. See Technical Bulletin for approved fastening systems for Paramount PVC Decking interior boards.
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.
Phantom Hidden Fasteners are backed by a 20-year limited residential warranty and a 5-year limited commercial warranty. For details, see complete warranty information.

Fiberon approved fasteners are designed to accommodate normal dimensional changes without material fracture or change in holding capability and are recommended for installation of Fiberon decking products. Any use of unapproved fasteners, including biscuits or nails, may lead to product failure and void the product warranty.
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:
**Cutting grooves or slots into deck boards may void the manufacturer's warranty. Fiberon does not warrant or guarantee your warranty will remain valid.
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
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.
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.
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.
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.
