The Simpson Strong-Tie HTT5KT Heavy Tension Tie Kit is a single-piece formed holdown engineered to resist medium tension loads in post-pour, concrete-to-steel connections. Built from 11-gauge steel with a rivet-free, four-ply formed seat, this tension tie attaches with #10 Strong-Drive SD Connector screws and accepts a 5/8 in. anchor rod - no separate washers required. The kit ships complete with the HTT5 holdown, a BP 5/8-2 bearing plate washer, and 26 #10 x 2-1/2 in. Strong-Drive SD Connector screws, making it ready to install straight out of the box for both retrofit and new construction applications.

Key Features

• Four-ply formed steel seat, no rivets - delivers increased tension capacity through a robust, single-piece construction that eliminates potential weak points associated with riveted designs.
• Anchor bolt washers not required - the four-ply seat geometry removes the need for separate washers, reducing hardware count and simplifying the installation process.
• Compatible with cast-in-place or post-installed anchor bolts - gives contractors the flexibility to use this holdown in a wide range of framing scenarios, from ground-up builds to structural retrofits.
• Sold as a complete kit - includes the HTT5 holdown, BP 5/8-2 bearing plate washer, and 26 #10 x 2-1/2 in. Strong-Drive SD Connector screws so everything needed for a full installation arrives together.
• 11-gauge steel with G90 zinc galvanized finish - the heavier gauge provides structural integrity under tension loading, while the G90 coating offers durable corrosion resistance across a variety of construction environments.
• Ideal for retrofit or new construction projects - versatile application compatibility means this tension tie fits naturally into both planned structural assemblies and after-the-fact strengthening work.

Why This Product

• Everything in one kit, nothing extra to source - because the holdown, bearing plate washer, and all 26 connector screws are included, contractors avoid last-minute hardware runs and can move directly from delivery to installation.
• Washer-free design cuts steps without cutting corners - the four-ply formed seat eliminates anchor bolt washers by design, streamlining the connection without compromising the load-resisting performance the holdown is built to deliver.
• Flexible anchor bolt compatibility keeps schedules on track - working with both cast-in-place and post-installed anchors means this tension tie adapts to real-world site conditions rather than forcing a specific sequencing of trades.
• Made in the United States to Simpson Strong-Tie standards - domestic production under a recognized structural connector brand supports consistent quality control for a component that carries meaningful tension loads in framing assemblies.
