Frequently Asked Questions

What type of decking is this fastener system compatible with?

The EB-TY EB14W 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%. It is not recommended for use with decking that exceeds this moisture threshold.

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

The patented EB-GUIDE predrill guide is designed to provide precise fastener angle alignment, ensuring consistent biscuit installations throughout your project. Two EB-GUIDE predrilling tools are included in this kit, along with two 1/8 in. quick-release impact-ready drill bits for immediate use.

Why are Type 316 stainless-steel screws used with this system?

The Type 316 stainless-steel trim-head, 6-lobe screws are selected for their corrosion resistance and durability, making them well-suited for demanding environments such as docks and boardwalks. Their black-painted heads provide a concealed finish that blends in with the EB-TY biscuit for a clean, professional appearance.

How does the stainless-steel reinforcing plate in the biscuit benefit the installation?

Simpson Strong-Tie integrated a Type 300 series stainless-steel reinforcing plate into the biscuit design to add stiffness, which holds boards in place securely and increases pullover resistance. At the same time, the design maintains flexibility to accommodate the natural seasonal contraction and expansion of decking boards.
