EB-TY® Premium Hidden Deck-Fastening System™ 

EB-TY® Premium Hidden Deck-Fastening System™

On This Page

The new EB-TY Premium Hidden Deck-Fastening System is the ideal solution that blends strength with ease of installation in a fastener that won't detract from the deck's finished appearance. Simpson Strong-Tie has redesigned the award-winning EB-TY Hidden Deck-Fastening System by integrating a Type 300 series stainless-steel reinforcing plate that adds stiffness to hold boards in place securely, yet maintains flexibility when seasonal contraction and expansion occur. Combine this innovative new design with our EB-GUIDE predrilling tool, and you have a system that not only provides hidden strength, but is also easy to install.

Key Features

  • Easy to install for professional builders and DIYers
  • Ideal for premium hardwoods

Metal Reinforced

  • Provides greater holding power and increased pullover resistance

Angled Screw Attachment

Radius Sides for Easier Alignment

  • 3/16" and 1/4" spacings offer expansion compensation

Covers the Joist

  • Protection from direct exposure to sun and rain
  • Visually more appealing after installation
