Hidden Deck Fasteners

Decking can be installed with hidden fasteners to create a clean looking surface that is smooth to bare feet.  Hidden fasteners can be used with composite, vinyl, cedar, ipe or other exotic hardwood material.  Many manufactured decking materials offer deck boards that are sold with a grooved edge for use with hidden fasteners.  You can also router the edges of solid deck boards to create a slot to accept deck clips.  It is important to note that pregrooved boards do not have a standard groove size. You should verify that hidden fasteners are compatible with your choice of decking boards before ordering.

Here are descriptions of the most popular hidden fastener systems.


Camo Hidden Fasteners

Camo Hidden Deck Fastening System:  This system uses the Camo Marksman tool to install deck screws at an angle into the side of the deck board to create a fastener free floor surface.  The Camo system can be used for all types of composite, PVC or solid wood decking materials and come with a Limited Lifetime Warranty. You can purchase stainless steel or protech coated screws in 1-7/8" for 5/4 decking and 2-3/8" for 2x6 decking.


Eb-Ty Hidden Deck Fastener

Eb-Ty:  This oval shaped biscuit type hidden fastener is made from polypropylene plastic and is designed to fit in the slotted edge of decking boards to create a screw free deck surface.  Eb-Ty is available in the following profiles:  Original:  Provides a 3/32" or 1/4" board spacing for Ipe, Redwood, Cedar and Correct Deck Composite.  Mini:  This profile has lower height for thinner deck boards.  The live cylinder series can absorb up to a 5/32" expansion of deck material.  This is ideal when working with composite decking in cold weather climates.  The top screw series spaces decking at 1/8" or 3/16" for certain brands of composite decking.  Swan secure #7 2-1/4" stainless steel screws are ideal for installation with the Eb-Ty system.  Eb-Ty is  manufactured in the USA.
