Frequently Asked Questions

What type of decking is this fastener system compatible with?

This system 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%. It is intended for wood deck board applications.

Why does this kit include Type 316 stainless-steel screws instead of a lower-grade fastener?

Type 316 stainless-steel trim-head, 6-lobe screws are included because they provide superior corrosion resistance in demanding outdoor environments. Their black-painted heads also provide a concealed finish that blends in with the EB-TY biscuit for a clean, professional appearance.

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

The patented EB-GUIDE predrill guide provides precise fastener angle alignment for consistent biscuit installations. It helps ensure every fastener is driven at the correct angle, resulting in uniform board spacing and reliable holding performance throughout the entire deck installation.

How does the stainless-steel reinforcing plate improve performance over standard hidden deck fasteners?

The integrated Type 300 series stainless-steel reinforcing plate adds stiffness to hold boards securely in place while still maintaining the flexibility needed to accommodate seasonal wood expansion and contraction. This redesigned feature also increases pullover resistance compared to non-reinforced biscuit fasteners.
