The Simpson EB-TY EB14W Premium Hidden Deck Fastener Kit with 1-5/8 in. Type 316 Stainless-Steel Screws delivers a professional hidden deck-fastening solution that combines structural strength with a clean, hardware-free finished surface. Simpson has redesigned this award-winning system by integrating a Type 300 series stainless-steel reinforcing plate that holds boards securely in place while maintaining the flexibility needed to accommodate seasonal expansion and contraction - making it a reliable choice for decks, docks, and boardwalks. The complete kit includes EB-TY Premium biscuits, stainless-steel screws, Ipe wood plugs, and the full suite of installation tools needed to get the job done right.

Key Features

• Patented EB-GUIDE predrill guide provides precise fastener angle alignment - ensures consistent biscuit installations across the entire deck surface, reducing guesswork and misalignment during installation.
• Stainless-steel reinforced biscuit design - adds stiffness and increased pullover resistance so boards stay locked in position even under load or heavy foot traffic.
• Underside keel provides consistent fastener positioning - keeps each biscuit properly seated during installation for uniform board spacing and a professional result every time.
• Radius sides and chamfered edges - allow easier alignment and faster installation, reducing the time spent fitting each fastener between boards.
• Type 316 stainless-steel trim-head, 6-lobe screws with black-painted heads - provide a concealed finish that blends in with the EB-TY biscuit, keeping the deck surface free of visible hardware.
• T-15 6-lobe driver bit included - engineered to reduce cam outs during driving, protecting both the screw head and the surrounding decking material.
• 1/8 in. quick-release impact-ready drill bit included - compatible with impact drivers for faster, more efficient predrilling without switching tools.
• Ipe wood plugs included for first and last board installations - allow clean concealment of direct-fastened end boards so the finished deck looks consistent from edge to edge.
• Designed for roof decks installed on 1 in. sleepers - the EB14WP series with 1-5/8 in. screws is specifically suited for this application, expanding the system's versatility beyond standard ground-level decking.

Why This Product

• A complete, ready-to-install hidden fastening system - unlike basic fastener packs, this kit includes the biscuits, screws, Ipe plugs, predrilling tool, drill bit, and driver bit, so contractors and serious DIYers have everything needed to complete the job without sourcing additional components separately.
• Engineered flexibility meets structural reinforcement - the integrated stainless-steel reinforcing plate is specifically designed to allow seasonal wood movement while still holding boards firmly, addressing one of the most common failure points in hidden deck fastener systems.
• Patented installation tooling takes the guesswork out of alignment - the included EB-GUIDE predrilling tool ensures every fastener is driven at the correct angle, delivering consistent results across large deck and boardwalk projects where uniformity matters most.
• Type 316 stainless-steel hardware throughout - provides a higher level of corrosion resistance than standard stainless options, making this system well suited for moisture-exposed applications such as docks, boardwalks, and coastal deck builds.

Frequently Asked Questions

What decking thickness is the EB14W biscuit designed for?

The EB14W biscuit is designed for decking with a thickness of 3/4 in. and requires a 1/4 in. board spacing to ensure proper installation and fitment.

Why does this kit include more screws than biscuits?

The kit includes 175 EB-TY Premium biscuits and 190 stainless-steel screws. The additional screws account for the first and last board installations, which require a direct-fastening approach assisted by the included Ipê wood plugs.

What is the purpose of the EB-GUIDE predrilling tool?

The patented EB-GUIDE predrilling tool is included to provide precise fastener angle alignment, ensuring consistent biscuit installations throughout the decking project and reducing the risk of misalignment or cam outs.

Are these fasteners suitable for use on roof decks and boardwalks?

Yes. The EB332WP, EB14WP, and EB316WP series with 1-5/8 in. screws are specifically designed for roof decks installed on 1 in. sleepers. The system is also approved for dock and boardwalk applications, and the Type 316 stainless-steel screws provide durability in demanding environments.
