The Simpson HTT5-3/4 Heavy Tension Tie for 3/4-in. Anchor is a Simpson Strong-Tie engineered connector built to resist medium tension loads in high-strength, post-pour, concrete-to-steel connections. This single-piece formed heavy tension tie features a four-ply formed seat, requires no rivets, and eliminates the need for anchor bolt washers - delivering reliable performance in both retrofit and new construction applications where structural uplift resistance is critical.

Key Features

• Four-ply formed steel seat - provides increased tension capacity in a single-piece design, reducing points of potential failure compared to multi-component assemblies
• No anchor bolt washers required - simplifies installation and reduces the number of hardware components needed on the job site
• Compatible with cast-in-place or post-installed anchor bolts - gives contractors flexibility to use the connector on new pours or retrofit projects without sourcing a different product
• Suitable for retrofit and new construction - a single connector solution that adapts to a wide range of project types and site conditions
• 11-gauge steel construction - delivers the structural strength needed for demanding concrete-to-wood or concrete-to-steel tension connections
• G90 zinc galvanized finish - provides corrosion resistance for use in construction environments where moisture exposure is a concern
• Fastens with #10 screws or common nail sizes - works with widely available fastener options, including Simpson Strong-Drive SD Connector screws, keeping procurement straightforward

Why This Product

• Engineered for medium tension load resistance - the four-ply formed steel seat is specifically designed to handle the uplift and tension forces present at concrete-to-wood connections, making this a purpose-built solution rather than a general-purpose strap
• Streamlined installation with fewer components - because no washers or rivets are required, the HTT5-3/4 reduces hardware complexity and speeds up installation, whether you are working on a retrofit or new build
• Versatile anchor bolt compatibility - acceptance of both cast-in-place and post-installed 3/4-in. anchor bolts means this connector fits naturally into a variety of framing and foundation workflows without design compromises
• American-made with lasting corrosion protection - backed by Simpson Strong-Tie manufacturing standards and finished with a G90 galvanized coating for durability in moisture-prone construction environments
