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 (approximately 19%). It maintains a consistent 1/4 in. board spacing during installation.

What makes the EB-TY Premium biscuit different from standard hidden deck fasteners?

Simpson Strong-Tie redesigned the EB-TY system by integrating a Type 300 series stainless-steel reinforcing plate into each polypropylene biscuit. This plate adds stiffness to hold boards firmly in place while still allowing the flexibility required to accommodate seasonal wood contraction and expansion.

What is the EB-GUIDE tool included in this kit, and how does it help?

The EB-GUIDE is a patented predrilling guide tool that provides precise fastener angle alignment, ensuring consistent biscuit installations across every board. Two EB-GUIDE tools are included in this 275-pack kit, along with two 1/8 in. quick-release impact-ready drill bits and two T-15 6-lobe driver bits to support efficient installation.

How are the screws in this kit designed to maintain a hidden appearance?

The kit includes Type 305 stainless-steel trim-head, 6-lobe screws with black-painted heads. The black finish is specifically designed to blend in with the EB-TY biscuit color, keeping all hardware concealed beneath the deck surface for a clean, polished finished appearance.
