How to Install Composite Deck Boards with TurboClip® Hidden Fastener System

Building a composite deck should be fast, beautiful, and seamless. In Part 5 of our Armadillo Decking series, we show how to install composite deck boards using the TurboClip hidden fastener system. This step-by-step guide helps DIY homeowners and professional installers achieve a polished, professional-looking deck with hidden fasteners, reducing installation time while ensuring a perfectly aligned, seamless finish.

Step 1: Start with Transition Boards

When moving from a solid edge board to a grooved board, begin with a stainless steel C-clip as a starter. The groove of the next deck board slides neatly under the C-clip’s lips, locking the boards together securely. This step ensures your composite decking boards start perfectly aligned.

The TurboClip hidden fastener system simplifies installation and saves time. Key benefits include:

  • Automatically creating a 3/16-inch gap between boards for proper spacing

  • Securing boards with a T15 screw—no special tools required

  • Allowing boards to snap quickly into place for a clean, professional appearance

Step 3: Achieve a Seamless Deck Installation with Directional Design

TurboClip fasteners feature an angled crush block on the underside. As the screw is tightened:

  • The board is locked securely in place

  • The fastener stays aligned, preventing shifting

  • The clip levels perfectly on the joist for a smooth, uniform surface

This directional design ensures every board is tightly secured, contributing to a seamless deck installation.
