The Simpson EB-TY EB332W Premium Hidden Deck Fastener Kit is a complete hidden fastening solution engineered for wood and composite deck boards, docks, boardwalks, and roof decks installed on 1 in. sleepers. Each polypropylene biscuit incorporates a Type 300 series stainless-steel reinforcing plate that locks boards firmly in place while allowing the natural flex needed to handle seasonal expansion and contraction - delivering a structurally sound deck surface with no exposed hardware in sight. The included EB-GUIDE predrilling tool and full accessory complement mean every component required for a clean, professional installation ships in a single kit, from first board to last.

Key Features

• Patented EB-GUIDE predrill guide provides precise fastener angle alignment - ensures consistent biscuit positioning across every board so installations stay uniform and professional without repeated measuring or guesswork.
• Stainless-steel reinforced polypropylene biscuit - the integrated reinforcing plate adds stiffness for a secure hold while maintaining enough flexibility to accommodate seasonal wood movement, protecting board integrity over time.
• Increased pullover resistance - the stainless-steel reinforced biscuit design keeps boards anchored under load, reducing the risk of boards lifting or shifting after installation.
• Underside keel provides consistent fastener positioning - registers the biscuit in the correct location automatically, reducing installation errors and speeding up the work on large deck runs.
• Radius sides and chamfered edges - allow the biscuit to seat and align faster during installation, cutting labor time without compromising fit or holding power.
• Type 316 stainless-steel trim-head, 6-lobe screws with black-painted heads - blend seamlessly with the EB-TY biscuit for a concealed finish, while the 6-lobe drive pattern reduces cam-outs and keeps installation moving efficiently.
• Kit includes Ipe wood plugs, EB-GUIDE tool, quick-release drill bit, and T-15 driver bit - every accessory needed to complete the job, including first and last board plugs, arrives together so no additional tool sourcing is required before work begins.

Why This Product

• Completely hidden fastening from start to finish - the biscuit-based system keeps all hardware concealed beneath the deck surface, producing a clean, uninterrupted board face that surface screws and clip systems simply cannot match in finished appearance.
• Redesigned for strength and seasonal flexibility in one - Simpson integrated a stainless-steel reinforcing plate into the award-winning EB-TY design specifically to solve the tradeoff between rigidity and movement tolerance, so boards stay locked in place without cracking or buckling as conditions change.
• Everything included for a complete installation - with biscuits, Type 316 stainless-steel screws, Ipe plugs, the EB-GUIDE predrilling tool, a quick-release drill bit, and a T-15 6-lobe driver bit all in one kit, contractors and serious DIYers can go from unboxing to finished deck without hunting for additional hardware.
• Versatile across multiple demanding applications - approved for wood decking, composite deck boards, docks, boardwalks, and roof decks on 1 in. sleepers, this system adapts to a wide range of project types without requiring a different fastener for each application.
