An inventive way to build your family's outdoor space with a fastener-free deck surface, the EB-TY fastener from Simpson Strong-Tie conceals the hidden deck fasteners onto the sides of the deck boards. Made from long-lasting polypropylene and fastened down with a corrosion-resistant stainless steel screw, the EB-TY biscuit fastener inserts perfectly into the pre-grooved or slot cut openings in the sides of the deck boards for a hardware and screw-free appearance that is safe for barefeet and snow shovels without worry. Make your deck work for you no matter the deck board material you love with the long-term performance of the EB-TY Deck Fastener by Simpson Strong-Tie. Choose between the impressive corrosion resistance of Grade 305 stainless steel screws or the near-indestructible Grade 316 stainless steel screws perfect for coastal and saltwater applications.

Use the 3/16 inch deck board spacing with thicker kiln-dried decking.

Simpson Strong-Tie EB-TY Deck Fasteners will include the biscuit fasteners, plugs for starter and end deck boards, and all installation hardware.

EB-TY Hidden Deck Fasteners are available in packs of 100 to cover approximately 50 square feet, a pack of 175 to cover approximately 100 square feet, and a pack of 275 to cover approximately 160 square feet.
