The Simpson Strong-Tie EB-TY EB332W Premium Hidden Deck-Fastening System (Model EB332WDR175) is the ideal solution that blends strength with ease of installation in a fastener that won't detract from the deck's finished appearance. Simpson Strong-Tie has redesigned the award-winning EB-TY Hidden Deck-Fastening System by integrating a Type 300 series stainless-steel reinforcing plate that adds stiffness to hold boards in place securely, yet maintains flexibility when seasonal contraction and expansion occur. Combine this innovative new design with the included EB-GUIDE predrilling tool, and you have a system that not only provides hidden strength, but is also easy to install. This kit includes 175 EB-TY Premium biscuits along with all the hardware and tooling needed for a complete, professional installation.

Frequently Asked Questions

What is included in this kit?

This kit includes 175 EB-TY Premium biscuits, 190 Type 305 stainless-steel trim-head screws, 12 Ipê wood plugs for first and last board installations, one EB-GUIDE predrilling tool, one 1/8 in. quick-release impact-ready drill bit, and one T-15 6-lobe driver bit.

What decking thickness and wood moisture content is this fastener system designed for?

The EB-TY Premium system is designed for decking that is 3/4 in. thick or greater, and it is intended for use with wood that has a moisture content greater than air dry, which is approximately 19% or higher.

What board spacing does this system create between deck boards?

The EB-TY Premium biscuits are designed to maintain a consistent spacing requirement of 3/32 in. between deck boards. The underside keel on each biscuit helps ensure this consistent positioning across every board during installation.

How does the redesigned EB-TY Premium biscuit differ from earlier versions?

Simpson Strong-Tie redesigned the EB-TY system by integrating a Type 300 series stainless-steel reinforcing plate directly into the polypropylene biscuit. This plate adds stiffness to hold boards in place securely while still maintaining flexibility to accommodate seasonal contraction and expansion. The biscuits also feature radius sides and chamfered edges for easier alignment and faster installation.
