Product Description
The Simpson EB-TY EB316W Premium Hidden Deck Fastener Kit with 2-1/4 in. Type 316 Stainless-Steel Screws (275-Pack) by Simpson Strong-Tie is a complete hidden deck-fastening solution engineered to deliver a clean, screw-free finished surface without sacrificing holding strength. Simpson Strong-Tie redesigned this award-winning system with an integrated Type 300 series stainless-steel reinforcing plate that adds stiffness to keep boards firmly in place while maintaining the flexibility needed to handle seasonal expansion and contraction. Combined with the included patented EB-GUIDE predrilling tool, this kit makes professional-quality hidden fastener installations straightforward and repeatable - whether you are working with wood deck boards, dock planking, or boardwalk applications.
Key Features
- Patented EB-GUIDE predrill guide provides precise fastener angle alignment for consistent biscuit installations - every fastener seats at the correct angle without guesswork, producing uniform results across the entire deck surface.
- Stainless-steel reinforced biscuit provides strength and increased pullover resistance - boards are held more securely against uplift and lateral movement, extending the long-term integrity of the deck.
- Underside keel provides consistent fastener positioning - eliminates shifting during installation so each biscuit locks into the same repeatable location, speeding up the workflow.
- Radius sides and chamfered edges provide easier alignment and faster installation - the biscuit seats into the board groove smoothly, reducing adjustment time and minimizing installation errors.
- Type 316 stainless-steel trim-head, 6-lobe screws with black-painted heads provide a concealed finish and blend in with EB-TY biscuit - hardware stays hidden and visually consistent, preserving the clean look of a hidden-fastener deck.
- T-15 6-lobe driver bit for reduced cam outs is included - the matching driver bit engages the screw head securely, protecting both the fastener and the surrounding decking surface during driving.
- 1/8 in. quick-release impact-ready drill bit is included - compatible with impact drivers for faster predrilling without switching tools or losing momentum on the job.
- Ipe wood plugs for first and last board installations are included - allows perimeter boards to be face-fastened and then concealed, maintaining a finished, uniform appearance from edge to edge.
Why This Product
- A truly complete system in one kit - biscuits, Type 316 stainless-steel screws, Ipe plugs, two EB-GUIDE predrilling tools, two drill bits, and two driver bits are all included, so there is no need to source additional hardware or accessories before starting the installation.
- Hidden fastening that holds up over time - the integrated stainless-steel reinforcing plate adds structural stiffness and pullover resistance while still allowing the biscuit to flex with seasonal wood movement, addressing one of the most common long-term failure points of hidden deck fasteners.
- Engineered for corrosion-prone outdoor environments - Type 316 stainless-steel screws provide superior corrosion resistance compared to standard grades, making this kit well-suited for docks, boardwalks, and coastal or high-moisture deck applications.
- Designed to save time on installation - the patented EB-GUIDE tool, chamfered biscuit edges, and impact-ready drill bit work together to reduce alignment adjustments and cam outs, keeping the installation moving efficiently without compromising accuracy.

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.
