Frequently Asked Questions

What type of decking is this fastener system compatible with?

The EB-TY EB316W Premium Hidden Deck Fastener is designed for use with 3/4-in. or greater kiln-dried decking that has a moisture content less than air dry, which is approximately 19%. The system requires a 3/16 in. board spacing.

What is the purpose of the EB-GUIDE predrilling tool included in this kit?

The patented EB-GUIDE predrill guide is included to provide precise fastener angle alignment, ensuring consistent biscuit installations every time. It takes the guesswork out of positioning and helps deliver a uniform, professional result across every deck board.

How does the stainless-steel reinforcing plate improve performance?

Simpson Strong-Tie integrated a Type 300 series stainless-steel reinforcing plate directly into the redesigned biscuit. This plate adds stiffness to hold boards securely in place while still allowing the flexibility needed to accommodate natural wood expansion and contraction that occurs with seasonal changes, increasing both strength and pullover resistance.

Are the screws included in this kit, and will they be visible after installation?

Yes, this kit includes 115 Type 305 stainless-steel trim-head, 6-lobe screws. The screws feature black-painted heads specifically designed to blend in with the EB-TY biscuit, providing a concealed finish so fasteners remain hidden in the completed deck surface.
