Hidden Deck Fasteners for Your Next Job

Hidden deck fasteners are a great way to level up your deck business by helping you build stronger, safer, and more elegant decks. We have created a guide with the differences between hidden fasteners and deck screws, from composite decking to grooved traditional wood deck boards. Plus, we’ve included tips and tools for installation before your next deck job.

Hidden Fasteners vs. Deck Screws

The humble deck screw is a classic for a reason. Deck screws are a budget-friendly option that are easy to install. However, hidden deck fasteners provide a variety of benefits to consider:

  • No more stubbed toes. Screw heads or other exposed fasteners can protrude above the deck boards making it easy to stub your toe. Hidden fasteners, being installed between the boards, won’t hurt bare feet or become a trip hazard.
  • Lower maintenance. As the hidden fasteners are not exposed to the elements, they are unlikely to rust increasing their durability and longevity.
  • Uniform gaps. Spacing is important when placing deck boards for structural integrity, drainage, ventilation, and appearance. Composite decking often comes with spacing guides for hidden fasteners to ensure proper gaps between the boards.
  • Smooth finish. Hidden fasteners are like no-show socks with tennis shoes: they provide a desirable smooth surface that’s perfect for homeowners who want a clean look.

However, hidden fasteners may not be suitable for all projects. It’s important to consider: 

  • Learning curve. Installation of hidden fasteners is a more complex process than traditional deck screws and precision is important.
  • Increased cost. Deck screws are a cheaper option than most hidden fasteners and could be a deterring factor for a homeowner.
  • Replacement considerations. Since hidden fasteners can’t be seen, they are hard to get to if adjustments or fixes need to be made. If this is a concern for you, color-matched deck screws could be a better option. 
  • Compatibility. Specific brands or types of hidden fasteners aren’t compatible across all deck materials. It’s important to understand which type your deck boards require.
    • The build of your deck matters, too. Hidden fasteners are for decks more than 12 inches off the ground and not applicable for stairs. Boards should be six inches wide or less.

Types of Hidden Fasteners

There are several different types of hidden fasteners. Which one is right for your project will depend on whether you are using wood or composite boards. Here are a few options:

  • Below-Board Fasteners- As the name suggests, these fasteners are secured under the boards.
  • Clip Fasteners- Used, for wood and composite materials, these fasteners are slid into the grooves on the sides of the boards.
  • Screw-and-Plug- These are for solid-edge boards. The screw is countersunk below the surface of the board, then the hole is covered with a plug that matches the color of the board.
  • Color-Matched- These are classic deck screws but are considered hidden as they are the same color as the deck.

Tips and Tools for Installation

It's important to be prepared for your next job using hidden deck fasteners. One small screw can make a big impact. Here's what to keep in-mind:

  • Ensure the hidden fasteners you purchase are the manufacturer-recommended system for your decking materials.
  • Starter clips are used to secure the board. Pay special attention to spacing and alignment during this step.
  • When the fasteners are installed, make sure the spacing is correct to ensure the next board is in the right position.

Some of the tools needed for installation include:

  • Composite deck board spacing tool: ensures proper spacing between boards.
  • Guide tool: helps to install the system and is recommended by the manufacturer.
  • Clip installation tool: for clip fasteners to quickly clip on evenly.
