Product Description
The Simpson EB-TY EB316W Premium Hidden Deck Fastener Kit with 2-1/4 in. Type 316 Stainless-Steel Screws (175-Pack) by Simpson delivers a complete hidden deck-fastening solution engineered to blend strength with ease of installation while keeping the deck's finished surface clean and fastener-free. Each polypropylene biscuit incorporates an integrated Type 300 series stainless-steel reinforcing plate that adds stiffness to hold boards securely in place while maintaining the flexibility needed to accommodate seasonal expansion and contraction. Paired with the included patented EB-GUIDE predrilling tool and a full set of installation accessories, this kit is built for consistent, professional-quality results on wood deck boards and boardwalk applications alike.
Key Features
- Patented EB-GUIDE predrill guide provides precise fastener angle alignment - ensures consistent biscuit installations across every board, reducing guesswork and rework for a uniform finished deck.
- Stainless-steel reinforced polypropylene biscuit - adds structural stiffness and increased pullover resistance so boards stay firmly locked in position without sacrificing flexibility during seasonal wood movement.
- Underside keel for consistent fastener positioning - keeps each biscuit correctly located between boards so spacing and alignment stay uniform from start to finish.
- Radius sides and chamfered edges - allow faster, easier alignment during installation, reducing the time spent fitting each fastener into the board groove.
- Type 316 stainless-steel trim-head, 6-lobe screws with black-painted heads - provide a concealed finish that blends with the EB-TY biscuit, delivering hidden strength without visible hardware on the deck surface.
- T-15 6-lobe driver bit included - reduces cam-outs during installation for a cleaner, more controlled drive with less bit slippage and fewer stripped fasteners.
- 1/8 in. quick-release impact-ready drill bit included - works directly with the EB-GUIDE tool for fast, accurate predrilling without swapping bits or stopping to reconfigure your drill.
- Ipe wood plugs included for first and last board installations - allow the exposed screw locations at the beginning and end of a deck run to be concealed, maintaining a consistent hidden-fastener appearance across the entire surface.
- Compatible with 3/4 in. or greater kiln-dried decking with moisture content less than air dry (approx. 19%) - ensures reliable performance when installed within the correct material parameters, protecting the integrity of the fastening system over time.
Why This Product
- A truly complete installation kit - unlike systems that require separate tool purchases, this kit ships with the EB-GUIDE predrilling tool, impact-ready drill bit, driver bit, Ipe plugs, biscuits, and screws, so installers have everything needed to start and finish a hidden-fastener deck without additional sourcing.
- Engineered for both strength and seasonal flexibility - the integrated stainless-steel reinforcing plate inside each biscuit holds boards firmly against lateral movement while the polypropylene body flexes with natural wood expansion and contraction, addressing one of the most common failure points in hidden deck-fastening systems.
- Corrosion-resistant hardware rated for demanding environments - Type 316 stainless-steel screws offer a higher level of corrosion resistance than standard stainless grades, making this system well suited for dock, boardwalk, and coastal deck applications where moisture exposure is a factor.
- Precision-engineered for a cleaner, faster install - the combination of the EB-GUIDE alignment tool, chamfered biscuit edges, and 6-lobe cam-out-resistant driver bit minimizes installation errors and speeds up the fastening process, helping professionals and experienced DIYers achieve consistent results on every run of decking.
