Frequently Asked Questions

What type of decking is this fastener kit compatible with?

This kit is designed for use with 3/4 in. or greater kiln-dried wood deck boards with a moisture content less than air dry, which is approximately 19%. It is not recommended for use with decking that exceeds this moisture content level.

How does the EB-GUIDE predrilling tool help during installation?

The patented EB-GUIDE predrill guide provides precise fastener angle alignment for consistent biscuit installations. Each kit includes two EB-GUIDE predrilling tools along with two 1/8 in. quick-release impact-ready drill bits to make the predrilling process accurate and efficient.

What board spacing does this hidden deck fastener system require?

The EB-TY EB316W system requires a 3/16 in. spacing between deck boards. The underside keel on the biscuit and the radius sides with chamfered edges help maintain consistent spacing and enable faster, more accurate alignment during installation.

Why are Ipê wood plugs included in this kit?

The 20 included Ipê wood plugs are specifically designed for use on the first and last board installations, where hidden fastening may not be possible. These plugs allow the screw holes at the perimeter boards to be concealed, maintaining the clean, finished look that defines the EB-TY Premium Hidden Deck-Fastening System.
