The Simpson Heavy Embedded Truss Anchor delivers an engineered method to attach roof trusses securely to concrete and masonry walls, giving builders and contractors a reliable structural connection rated for both wind and seismic forces. Constructed from 16-gauge stainless steel, this heavy truss anchor features staggered nail patterns to strengthen uplift resistance and supports use in pairs on single- and multi-ply trusses. Its versatile design allows installation straight or field-bent around truss or rafter members, making it a highly adaptable choice for demanding roof-to-wall connections in exterior and treated-wood environments.

Key Features

• Indented embedment line built into the anchor - takes the guesswork out of installation by providing a clear, accurate depth reference when setting into a poured concrete bond beam or grouted block wall.
• Compatible with the Simpson Strong-Tie preassembled TSS snap-in seat - allows faster, more consistent truss seating when used alongside this matching accessory, reducing on-site assembly time.
• Load rated for wind and seismic forces - engineered to meet code requirements in high-wind and seismic zones, giving builders confidence in the structural integrity of the connection.
• 16-gauge stainless steel construction - delivers the strength of heavy-gauge steel with the added corrosion resistance needed for exterior applications and connections involving pressure-treated lumber.
• Installs straight or field-bent around truss or rafter members - adapts to varying job-site conditions without requiring special tools or pre-fabrication, improving installation flexibility.
• Usable individually or in pairs on single- and multi-ply trusses - a single anchor model handles a wider range of truss configurations, reducing the number of different connectors a contractor needs to stock.

Why This Product

• Built-in accuracy for faster, more reliable embedment - the indented embedment line eliminates measurement errors at the wall, ensuring every anchor is set to the correct depth the first time and reducing costly callbacks.
• Stainless steel finish stands up where standard galvanized hardware falls short - the stainless steel material provides extra corrosion resistance that makes this anchor a dependable choice for exterior roof connections and assemblies using treated wood, where long-term durability matters most.
• One anchor, multiple configurations - the ability to install straight or field-bent, and to use the same anchor on both single- and multi-ply trusses, means greater jobsite versatility and fewer SKUs to manage across a project.
• Engineered for the forces that matter most - with load ratings covering both wind uplift and seismic events, this heavy embedded truss anchor supports code-compliant roof framing in the most demanding structural environments.

Frequently Asked Questions

How deep does the HETA20SS need to be embedded?

The HETA20SS is designed to embed 4 in. into a poured concrete bond beam or grouted block wall. An indented embedment line is built into the anchor to ensure accurate embedment depth during installation.

What fasteners should be used to install the HETA20SS?

Install with stainless-steel 10d x 1-1/2 in. nails or stainless-steel 16d common nails to maintain the corrosion resistance of the connection assembly.

Can the HETA20SS be used with multi-ply trusses?

Yes. The HETA20SS can be used in pairs on both single- and multi-ply trusses, and it can be installed straight or field-bent around truss or rafter members for versatile on-site configuration.

Why choose stainless steel for this truss anchor?

The stainless-steel construction of the HETA20SS offers extra corrosion resistance, making it well suited for exterior applications and installations involving treated wood where standard steel connectors may be prone to accelerated corrosion.
