The Simpson EB-TY EB14W Premium Hidden Deck Fastener Kit with 2-1/4 in. Type 305 Stainless-Steel Screws delivers a concealed fastening solution for wood deck boards and dock or boardwalk surfaces that combines structural strength with a clean, hardware-free finished appearance. Simpson redesigned the award-winning EB-TY system by integrating a Type 300 series stainless-steel reinforcing plate into each polypropylene biscuit, adding stiffness to hold boards securely in place while maintaining the flexibility needed to accommodate seasonal wood expansion and contraction. Paired with the included EB-GUIDE predrilling tool, this kit makes hidden deck fastening precise, consistent, and straightforward from start to finish.

Key Features

• Patented EB-GUIDE predrill guide provides precise fastener angle alignment - ensures every biscuit is installed at a consistent angle, reducing installation errors and speeding up the overall workflow.
• Stainless-steel reinforced biscuit provides increased pullover resistance - the integrated Type 300 series reinforcing plate keeps boards locked firmly in place even as wood naturally moves with the seasons.
• Underside keel provides consistent fastener positioning - eliminates guesswork during placement so each fastener sits correctly and boards remain evenly aligned across the entire deck surface.
• Radius sides and chamfered edges - make biscuit alignment easier and installation faster, reducing friction and the effort needed to seat each fastener between boards.
• Type 305 stainless-steel trim-head, 6-lobe screws with black-painted heads - blend seamlessly with the EB-TY biscuit for a fully concealed finish, while the 6-lobe drive reduces cam-outs during installation.
• Designed for 3/4 in. or greater kiln-dried decking with moisture content less than air dry - ensures compatibility with properly prepared lumber and maintains reliable holding power over the life of the deck.
• Maintains a consistent 1/4 in. board spacing - delivers uniform gaps between deck boards for proper drainage and a professional finished look without manual measuring.
• Kit includes Ipe wood plugs, dual EB-GUIDE tools, quick-release drill bits, and T-15 driver bits - provides every component needed to complete first-board, field, and last-board installations without sourcing additional hardware separately.

Why This Product

• Truly hidden fastening with no surface hardware visible - the biscuit-style concealed system keeps all fasteners tucked between boards, so the finished deck shows only clean, uninterrupted wood - a result that face-screwing and many clip systems cannot match.
• Engineered to handle real-world wood movement - the stainless-steel reinforcing plate inside each polypropylene biscuit combines stiffness with controlled flexibility, meaning boards stay tight and flat through seasonal contraction and expansion without cracking or buckling.
• A complete system in one kit - with two EB-GUIDE predrilling tools, two quick-release drill bits, two T-15 driver bits, Ipe plugs for border boards, and matching screws all included, installers have every specialized component on hand to handle the entire deck from first board to last without interruption.
• Precision-engineered details that save time on the job - the patented EB-GUIDE alignment tool, underside keel, chamfered edges, and radius sides work together to speed up placement and reduce rework, making this system practical for both professional contractors and serious DIY deck builders.

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.
