Product Description
The Simpson EB-TY EB316W Premium Hidden Deck Fastener Kit with 1-5/8 in. Type 316 Stainless-Steel Screws (175-Pack) by Simpson is a redesigned, award-winning hidden deck-fastening system built for wood deck boards and roof deck applications where both structural performance and a clean, fastener-free surface are priorities. Each polypropylene biscuit features an integrated Type 300 series stainless-steel reinforcing plate that holds boards firmly in place while maintaining the flexibility needed to handle seasonal wood expansion and contraction - delivering lasting stability without a single visible fastener on the finished deck surface.
Key Features
- Patented EB-GUIDE predrill guide provides precise fastener angle alignment for consistent biscuit installations - eliminates guesswork during installation so every fastener is positioned correctly the first time, reducing errors and rework.
- Stainless-steel reinforced biscuit provides strength and increased pullover resistance - boards are held more securely than with unreinforced fasteners, giving the deck greater long-term structural integrity.
- Underside keel provides consistent fastener positioning - keeps each biscuit properly located between boards so spacing stays uniform across the entire deck surface.
- Radius sides and chamfered edges provide easier alignment and faster installation - the biscuit slides into place with less resistance, speeding up the installation process on large decking projects.
- Type 316 stainless-steel trim-head, 6-lobe screws with black-painted heads provide a concealed finish and blend in with the EB-TY biscuit - any screw that remains visible matches the biscuit color for a polished, professional result.
- Kit includes EB-TY Premium biscuits, stainless-steel screws, Ipe plugs, EB-GUIDE predrilling tool, 1/8 in. quick-release impact-ready drill bit, and T-15 6-lobe driver bit - everything needed for a complete hidden fastener installation arrives together, so there is no need to source additional tools or hardware separately.
- Designed for roof decks installed on 1 in. sleepers - the EB316WP series with 1-5/8 in. screws is suited for elevated roof deck applications, expanding the range of projects this system can handle.
Why This Product
- A truly complete installation system in one kit - unlike bare fastener packs that leave installers sourcing drill bits and driver bits separately, this kit bundles the EB-GUIDE predrilling tool, a quick-release drill bit, a T-15 driver bit, Ipe wood plugs, and screws alongside the biscuits, so the job can start immediately without additional purchases.
- Engineered to handle real-world wood movement - the integrated Type 300 series stainless-steel reinforcing plate within each biscuit balances stiffness with flexibility, holding boards firmly in place during normal use while allowing the natural seasonal expansion and contraction of wood decking to occur without cracking or distortion.
- Type 316 stainless-steel hardware for demanding environments - both the reinforcing plate and the included screws use corrosion-resistant Type 316 stainless steel, making this system well-suited for coastal, dock, boardwalk, and other high-moisture applications where standard fasteners would degrade prematurely.
- Hidden fastening for a clean, professional deck finish - because all fasteners are concealed within the grooves of the deck boards, the finished surface shows only uninterrupted wood grain, making this system the preferred choice for homeowners and contractors who want a premium aesthetic alongside proven structural performance.

Frequently Asked Questions
What makes the EB-TY Premium system different from standard hidden deck fasteners?
Simpson Strong-Tie redesigned the EB-TY system to include an integrated Type 300 series stainless-steel reinforcing plate within each polypropylene biscuit. This plate adds stiffness that holds boards securely while still allowing the flexibility needed to handle seasonal wood expansion and contraction - a combination not found in basic hidden fastener designs.
What decking thickness and board spacing is this fastener system designed for?
The EB316WP series is designed for decking with a thickness of 3/4 in. and requires a board spacing of 3/16 in. between deck boards for proper installation.
Is this kit appropriate for roof deck applications?
Yes. The EB332WP, EB14WP, and EB316WP series with 1-5/8 in. screws are specifically designed for roof decks installed on 1 in. sleepers, making this kit a suitable choice for that application.
What tools and accessories are included to help with installation?
Each kit includes the patented EB-GUIDE predrilling tool for precise fastener angle alignment, a 1/8 in. quick-release impact-ready drill bit, a T-15 6-lobe driver bit designed to reduce cam outs, and Ipê wood plugs for first and last board installations - providing everything needed for a professional hidden deck installation.
