The Simpson EB-TY EB316W Premium Hidden Deck Fastener Kit with 1-5/8 in. Type 316 Stainless-Steel Screws (175-Pack), model EB316WP316R175 by Simpson Strong-Tie, is an award-winning hidden deck-fastening system engineered for wood deck boards that demand both superior holding strength and a flawless finished appearance.

Frequently Asked Questions

What makes the EB-TY Premium system different from standard hidden deck fasteners?

Simpson Strong-Tie redesigned the EB-TY system to include an integrated Type 300 series stainless-steel reinforcing plate within each polypropylene biscuit. This plate adds stiffness that holds boards securely while still allowing the flexibility needed to handle seasonal wood expansion and contraction - a combination not found in basic hidden fastener designs.

What decking thickness and board spacing is this fastener system designed for?

The EB316WP series is designed for decking with a thickness of 3/4 in. and requires a board spacing of 3/16 in. between deck boards for proper installation.

Is this kit appropriate for roof deck applications?

Yes. The EB332WP, EB14WP, and EB316WP series with 1-5/8 in. screws are specifically designed for roof decks installed on 1 in. sleepers, making this kit a suitable choice for that application.

What tools and accessories are included to help with installation?

Each kit includes the patented EB-GUIDE predrilling tool for precise fastener angle alignment, a 1/8 in. quick-release impact-ready drill bit, a T-15 6-lobe driver bit designed to reduce cam outs, and Ipê wood plugs for first and last board installations - providing everything needed for a professional hidden deck installation.
