The Simpson EB-TY EB316W Premium Hidden Deck Fastener Kit with 2-1/4 in. Type 305 Stainless-Steel Screws from Simpson is the ideal solution for achieving a clean, fastener-free deck surface without sacrificing structural integrity. This redesigned, award-winning hidden deck-fastening system integrates a Type 300 series stainless-steel reinforcing plate that adds stiffness to hold boards securely in place while maintaining the flexibility needed to accommodate seasonal contraction and expansion. Paired with the included patented EB-GUIDE predrilling tool, this kit delivers consistent, professional-grade biscuit installations across wood deck boards and boardwalk applications alike.

Key Features

• Patented EB-GUIDE predrill guide provides precise fastener angle alignment - ensures every biscuit is installed at a consistent angle, eliminating guesswork and reducing costly installation errors.
• Stainless-steel reinforced biscuit - adds stiffness and increased pullover resistance so deck boards stay firmly held in place over time, even through seasonal movement.
• Underside keel - maintains consistent fastener positioning from board to board, resulting in a uniform, professional-looking deck surface.
• Radius sides and chamfered edges - allow easier alignment and faster installation, helping crews work more efficiently across large deck projects.
• Type 305 stainless-steel trim-head, 6-lobe screws with black-painted heads - blend seamlessly with the EB-TY biscuit for a fully concealed finish that preserves the deck's clean appearance.
• T-15 6-lobe driver bit included - reduces cam-outs during driving so fasteners seat cleanly without stripping or surface damage.
• Compatible with 3/4 in. or greater kiln-dried decking - use with wood decking at moisture content less than air dry (approximately 19%) to ensure a reliable, long-lasting connection.
• Ipe plugs included for first and last board installations - provide a finished look at deck borders where hidden fasteners alone cannot be used, maintaining a seamless appearance throughout.

Why This Product

• A complete, ready-to-install system - this kit includes biscuits, screws, Ipe plugs, the EB-GUIDE predrilling tool, a quick-release impact-ready drill bit, and a driver bit, so installers have every component needed to complete the job without sourcing additional accessories.
• Hidden fastening that holds up to real-world conditions - the integrated stainless-steel reinforcing plate balances rigidity with flexibility, keeping boards locked in position while allowing for the natural expansion and contraction that wood decking experiences across seasons.
• Precision-engineered for consistent results - the patented EB-GUIDE tool, underside keel, and chamfered biscuit edges work together to standardize installation angle and spacing, reducing variation and rework on every deck project.
• Built for both residential decks and demanding boardwalk applications - the polypropylene biscuit body paired with Type 305 stainless-steel hardware makes this system suitable for wood deck board installations where a clean, concealed fastening finish is required.

Frequently Asked Questions

What type of decking is the EB316W compatible with?

The EB-TY EB316W is designed for use with 3/4-in. or greater kiln-dried decking with a moisture content less than air dry (approximately 19%). It is well-suited for wood deck board applications where a hidden fastening finish is desired.

How much board spacing does the EB-TY system create between deck boards?

The EB-TY EB316W Premium Hidden Deck Fastener requires a 3/16 in. spacing between deck boards, which is built into the system's design to ensure consistent gaps across the entire deck surface.

What tools and accessories are included to assist with installation?

This kit includes the patented EB-GUIDE predrilling tool for precise fastener angle alignment, a 1/8 in. quick-release impact-ready drill bit, and a T-15 6-lobe driver bit designed to reduce cam outs - giving you everything needed for a complete and consistent installation right out of the box.

Why does this kit include more screws (190) than biscuits (175)?

The kit includes (190) Type 305 stainless-steel screws and (175) EB-TY Premium biscuits. The additional screws account for the Ipê wood plug installations at the first and last deck board positions, where boards are face-fastened and then concealed with the included (12) Ipê wood plugs rather than using the hidden biscuit method.
