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 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 comes 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 2×6 decking. Camo
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.
