The Simpson Heavy Embedded Truss Anchor from Simpson Strong-Tie provides an engineered method to attach roof trusses securely to concrete and masonry walls. Built from 16-gauge steel with a G90 zinc galvanized finish, this heavy-duty truss anchor delivers load-rated performance against wind and seismic forces. Its staggered nail patterns strengthen uplift resistance, and the versatile design supports straight installation or field-bending around truss or rafter members - making it a dependable solution for both single-ply and multi-ply truss connections on residential and commercial roof framing projects.

Key Features

• Indented embedment line - takes the guesswork out of installation by marking the exact embedment depth directly on the anchor, helping ensure a consistent, code-compliant connection every time.
• Load rated for wind and seismic forces - gives builders and inspectors confidence that the connection meets engineered performance requirements in demanding structural applications.
• 16-in. exposed length - provides ample surface area along the truss or rafter for a secure, well-distributed fastener connection.
• Compatible with straight or field-bent installation - adapts to different framing conditions without requiring additional hardware, saving time on the job site.
• Works in pairs on single- and multi-ply trusses - offers flexible use across a wide range of roof framing assemblies with a single anchor model.
• 16-gauge steel construction - delivers heavy-duty strength and dimensional consistency for a reliable structural connection.
• Zinc galvanized finish (G90) - provides extra corrosion resistance, helping the anchor hold up in environments where moisture exposure is a concern.
• Compatible with the Simpson Strong-Tie TSS truss seat snap-in and TBP8 moisture barrier plate - integrates seamlessly into a complete truss connection system, reducing the need to source incompatible components from other manufacturers.

Why This Product

• Engineered specifically for truss-to-wall connections - unlike generic hardware, this anchor is purpose-built to attach roof trusses to concrete beams and grouted masonry block walls, with load ratings that address real-world wind and seismic uplift demands.
• Built-in accuracy feature reduces installation errors - the indented embedment line ensures every installer sets the anchor at the correct depth without measuring, which helps maintain structural integrity across the entire roof system.
• Versatile enough to handle a range of framing scenarios - the ability to install straight or field-bent, combined with pairing capability for multi-ply trusses, means one anchor model covers multiple common roof framing configurations.
• G90 galvanized coating extends service life - the corrosion-resistant finish makes this anchor a practical choice for applications where the connection point may be exposed to moisture over the long term, reducing the risk of premature degradation.

Frequently Asked Questions

What is the required embedment depth for the HETA20?

The HETA20 must be embedded 4 in. into a 6-in. minimum concrete beam or an 8-in. nominal grouted block wall. The indented embedment line on the anchor helps ensure accurate embedment depth during installation.

What fasteners are recommended for installing the HETA20?

The HETA20 should be installed with 10d x 1-1/2 in. nails or 16d common nails for a proper and load-rated connection.

Can the HETA20 be used on both single-ply and multi-ply trusses?

Yes. The HETA20 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 flexible application.

Is the HETA20 compatible with any Simpson Strong-Tie accessory products?

Yes. The HETA20 is compatible with the Simpson Strong-Tie TSS truss seat snap-in and the TBP8 moisture barrier plate, making it easy to integrate into a complete truss connection system.
