Simpson Strong-Tie’s EB-TY® Hidden Deck Fasteners™are one of the most reliable, long-lasting hidden fasteners on the market. Made in the USA, the dark, ultra-violet resistant polypropylene hidden deck fasteners will not rust or shrink. Even at temperatures over 200 degrees Fahrenheit, EB-TY® will neither crack nor soften. Given its approximated life span of 100 years, the fastener saves the homeowner money on deck repair.

The EB-TY® Hidden Deck-Fastening System™consists of black biscuits that are inserted into slots or kerfs cut by a biscuit joiner, or router bit, at each joist. One stainless steel #7 2-1/4″ screw holds each biscuit tight. After applying beads of exterior construction glue to each joist, the next deck board slips over the exposed EB-TY® fasteners.

You work from the top surface when using EB-TY® fasteners, so you can build decks as close to the ground as you want, or even float them over flat roofs. Installation takes only one EB-TY® hidden deck fastener and one screw wherever a deck board intersects with a joist.

Which EB-TY size is right for your deck?

Air-dried (AD) decking such as Ipe Massaranduba:  Original EBE004 hidden deck fastener with 3/32″ spacing is recommended for 4/4″ and 5/4″ deck boards.

Kiln-dried (KD) decking such as Garapa, or spaces where you have limited air flow:  EBE005LC hidden deck fastener with a 1/4″ spacing is recommended for 4/4″ and 5/4″ deck boards.
