How Do I Know if Hidden Fasteners Will Work Well for My Deck?

Fastening your Mataverde Hardwood Decking with stainless steel deck screws directly to the wood joists is the strongest method to secure your deck boards.  However, many clients don't like the look of exposed screw heads on their deck boards, so hidden decking clips provide a fast and secure method for many job site installations.

It's important to know that when using a hidden decking fastener, you are often trading off strength for looks. There are some applications and job site conditions where hidden fastening will work well and others work best with deck screws. How can you tell? 

Best Conditions For Using Concealed Deck Fastening:

If your answers to the questions below are all "YES", then deck hidden fasteners are a good option to consider.

  • Will there be under-deck ventilation on three sides to allow air flow? (Adequate ventilation is the most critical factor affecting decking performance)
  • Is your deck a minimum of 30" above the ground? (the higher the better)

  • Does the ground below your deck pitch away from the house or structure?

  • Is there adequate drainage for rain water? (various landscape fabrics and gravel work well)

Best Decking Sizes to Use with Hidden Fastening:

  • Nominal '21 mm x 4' or '5/4 x 4' pre-grooved decking provides better strength and performance

  • Pre-grooved decking will save you time, money and labor...and it looks fantastic, too

Pre-grooved deck boards save lots of time, expense and aggravation. Choose from reliable hardwood decking species like Ipe, Machiche, Garapa and Cumaru. All four of these durable hardwood decking species are available pre-grooved and are covered by the Mataverde® 25 Year Limited Warranty. The continuous groove makes installing pre-grooved hidden fasteners faster and easier whether you are installing your deck boards square or diagonally.

Hidden Deck Fastener Installation

  • To install decking with the Mataverde Deck Clip fastener, lay out your deck boards, normally, one row at a time. Instead of drilling and screwing through the face of the deck boards, pre-drill the bottom edge of one side of the pre-grooved decking only, at a 45° degree angle.
  • Then screw the deck board into the joist. This seats and fastens the deck board securely. Pre-drill and screw the Mataverde Eurotec Deck Clip through the bottom edge of the pre-grooved deck board.jpg
  • Repeat the process at each joist location and continue with your next rows of decking.
