Frequently Asked Questions

What type of decking boards is the EB332W biscuit compatible with?

The EB-TY EB332W Premium Hidden Deck Fastener is designed for use with 3/4-in. or greater thickness wood decking boards that have a moisture content greater than air dry, which is approximately 19%. It is suitable for applications such as decks, docks, and boardwalks.

How does the stainless-steel reinforcing plate improve performance?

The integrated Type 300 series stainless-steel reinforcing plate adds stiffness to the polypropylene biscuit, which holds boards securely in place and provides increased pullover resistance. At the same time, it maintains enough flexibility to allow for the natural seasonal contraction and expansion of wood decking boards.

What tools are needed to install the EB-TY Premium Hidden Deck Fasteners?

All required installation tools are included in this kit. The EB-GUIDE predrilling tool provides precise fastener angle alignment for consistent biscuit installations. The kit also includes two 1/8 in. quick-release impact-ready drill bits and two T-15 6-lobe driver bits, which help reduce cam-outs during installation. No additional tools beyond a standard drill or impact driver are needed.

What is the required board spacing when using the EB332W fasteners?

A board spacing requirement of 3/32 in. is required when installing decking boards with the EB-TY EB332W Premium Hidden Deck Fastening System. The radius sides and chamfered edges of the biscuit are designed to assist with alignment and help achieve this consistent spacing more easily and efficiently during installation.
