Simpson EB-TY EB316W Premium Hidden Deck Fastener Kit with 2-1/4 in. Type 305 Stainless-Steel Screws from Simpson Strong-Tie is a complete hidden deck-fastening system engineered to deliver a clean, fastener-free surface on wood decks and dock boardwalks without sacrificing holding strength. The redesigned, award-winning EB-TY system integrates a Type 300 series stainless-steel reinforcing plate directly into the polypropylene biscuit, adding stiffness that holds boards firmly in place while preserving the flexibility needed to handle seasonal wood expansion and contraction. Combined with the included EB-GUIDE predrilling tool, this kit gives builders an accurate, repeatable installation process that results in consistent board spacing and a finished deck surface that looks as good as it performs.

Key Features

• Patented EB-GUIDE predrill guide provides precise fastener angle alignment - takes the guesswork out of biscuit placement, so every fastener goes in at the correct angle for consistent results across the entire deck surface.
• Stainless-steel reinforced biscuit with increased pullover resistance - the integrated Type 300 series reinforcing plate adds structural stiffness that holds deck boards securely and reduces the risk of boards lifting or shifting over time.
• Underside keel for consistent fastener positioning - keeps each biscuit properly seated during installation, minimizing shifting and helping maintain uniform board spacing from start to finish.
• Radius sides and chamfered edges on the biscuit - allow faster, easier alignment into the kerf slot, speeding up the installation process without compromising accuracy.
• Type 305 stainless-steel trim-head, 6-lobe screws with black-painted heads - blend seamlessly with the EB-TY biscuit for a fully concealed fastening result, while the 6-lobe drive design reduces cam-outs during driving.
• Designed for 3/4 in. or greater kiln-dried decking - compatibility with properly dried wood ensures the fastening system performs as intended and reduces the risk of movement or fastener failure caused by excess moisture in the boards.
• Maintains 3/16 in. board spacing - built-in spacing consistency promotes proper drainage and airflow beneath the deck surface, which helps extend the life of the wood.
• Complete kit includes biscuits, screws, Ipe wood plugs, EB-GUIDE tools, drill bits, and driver bits - everything needed for a full hidden fastener installation arrives together, eliminating separate accessory purchases and keeping the job moving.

Why This Product

• A truly complete hidden fastening solution in one kit - the inclusion of EB-GUIDE predrilling tools, quick-release impact-ready drill bits, T-15 driver bits, and Ipe wood plugs for first and last board installations means a builder can open one package and go, rather than sourcing each component separately.
• Steel-reinforced design balances rigidity with seasonal flexibility - unlike basic plastic biscuit fasteners, the integrated Type 300 series stainless-steel plate gives the polypropylene biscuit the added stiffness needed to resist pullover while still allowing the natural movement that wood decking requires through changing seasons.
• Precise predrilling tool eliminates guesswork and inconsistency - the patented EB-GUIDE guide ensures every biscuit is fastened at the correct angle, which is especially valuable on large decks or dock boardwalk projects where consistent spacing and alignment directly affect the finished appearance.
• Fastener-free surface protects the deck's visual appeal - because the biscuits and black-headed screws are fully hidden between boards, the finished deck surface shows only clean, uninterrupted wood, making this system well suited for projects where aesthetics matter as much as structural performance.
