Frequently Asked Questions

What type of decking is the EB316W compatible with?

The EB-TY EB316W is designed for use with 3/4-in. or greater kiln-dried decking with a moisture content less than air dry (approximately 19%). It is well-suited for wood deck board applications where a hidden fastening finish is desired.

How much board spacing does the EB-TY system create between deck boards?

The EB-TY EB316W Premium Hidden Deck Fastener requires a 3/16 in. spacing between deck boards, which is built into the system's design to ensure consistent gaps across the entire deck surface.

What tools and accessories are included to assist with installation?

This kit includes the patented EB-GUIDE predrilling tool for precise fastener angle alignment, a 1/8 in. quick-release impact-ready drill bit, and a T-15 6-lobe driver bit designed to reduce cam outs - giving you everything needed for a complete and consistent installation right out of the box.

Why does this kit include more screws (190) than biscuits (175)?

The kit includes (190) Type 305 stainless-steel screws and (175) EB-TY Premium biscuits. The additional screws account for the Ipê wood plug installations at the first and last deck board positions, where boards are face-fastened and then concealed with the included (12) Ipê wood plugs rather than using the hidden biscuit method.
