Trex Hideaway® Hidden Fastening System

In pursuit of the perfect deck, all Trex® decking lines come with a hidden installation option. When using grooved-edge boards, our hidden deck 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.
