Simpson EB-TY Hidden Deck Fastener for Composite Decking (Model No. 175-EBTYP) by Simpson is a polypropylene biscuit fastener system designed to deliver a clean, fastener-free deck surface when installing composite deck boards. The EB-TY fits into a slot cut into the edge of each deck board using a standard biscuit joiner, allowing all fastening to be done from the top side while keeping hardware completely out of sight. With 175 fasteners per bucket, this package provides enough material to install 100 square feet of decking, and consistent board spacing and uniform height are automatically achieved by nesting each successive board against the installed biscuit.

Frequently Asked Questions

How do EB-TY fasteners create an invisible deck surface?

The EB-TY is a biscuit fastener that fits into a slot cut into the edge of each deck board using a standard biscuit joiner. Because fastening is done into the side of the board rather than through the face, no screw heads appear on the deck surface, making the fasteners virtually invisible once the boards are installed.

What tool is needed to cut the slots for EB-TY fasteners?

A standard biscuit joiner is used to cut the slot into the edge of each deck board. The EB-TY biscuit fastener is then inserted into that slot and secured with a screw driven through the biscuit and into the joist.

How much decking can one 175-piece bucket of EB-TY fasteners cover?

Each EB-TY package includes enough EB-TY fasteners and screws to install 100 square feet of decking.

How is consistent board spacing ensured when using EB-TY fasteners?

Nesting each successive deck board against the installed EB-TY fastener automatically ensures consistent 3/16" spacing between boards and maintains uniform height across the deck surface, eliminating the need for manual spacing tools between boards.
