Trex Hidden Fasteners

Trex is committed to innovation, right down to efficient installation techniques, smart tools and hidden deck fasteners, an elegant upgrade to face screws.  The Trex Hideaway® Hidden Fastening System installs between the deck boards, fastening them to the joists with no visible deck screw heads on the walking surface. This precision also creates perfectly consistent spacing between the boards for a flawless look across the entire deck. This system includes a few simple components:

  • The Universal Fastener – This self-gapping hardware is the main fastener component that attaches two boards together. It features a stainless steel deck screw already set in the fastener for increased durability and easier installation. Available in versions for Trex Elevations® steel framing or for wood framing.
  • The Start Clip & Connector Clip – These are black, stainless steel fasteners designed exclusively for Trex and used to install the perimeter deck boards.
  • Trex Router Bit (Groove Cutter) – Traditional square edge boards require traditional deck screws for installation; however, using a Trex® groove cutter routes the necessary underside groove into any traditional board to accommodate our hidden deck fastening system
  • Gun Pail – This complete system includes all the components necessary for hidden deck fastener installation of a 500-square-foot deck with a pneumatic gun, including connector deck clips, pneumatic deck screws and complete installation instructions.
