Product Description
Simpson ATR 7/8 in. x 24 in. Hot-Dip Galvanized All-Thread Rod is a fully threaded steel rod from Simpson, engineered as a tension transfer element for use with Simpson Strong-Tie adhesives. The hot-dip galvanized finish delivers reliable corrosion resistance in demanding conditions, making this all-thread rod a dependable choice for structural anchoring applications such as floor-to-floor holdowns and a wide range of other anchoring solutions where durability and consistent thread engagement matter.
Key Features
- Fully threaded along the entire length - provides maximum flexibility when cutting or positioning the rod within structural assemblies, eliminating dead zones where fasteners cannot engage
- Hot-dip galvanized coating - offers extra corrosion resistance beyond standard zinc-plated finishes, keeping this rod performing reliably in exterior environments and treated-wood applications where moisture exposure is a concern
- Cut to length for convenience - allows installers to trim the rod to the exact dimension needed on site, reducing waste and simplifying the anchoring process
- UNC Class 2A or 1A thread specifications - conforms to standard Unified National Coarse thread designations, ensuring broad compatibility with compatible nuts, couplers, and structural hardware
Why This Product
- Purpose-built for adhesive anchoring systems - designed specifically as a tension transfer element for use with Simpson Strong-Tie adhesives, giving structural contractors a rod that is matched to a proven anchoring system rather than a generic alternative
- Superior corrosion protection for tough environments - the hot-dip galvanization process provides heavier, more durable coating coverage than zinc plating, making this rod well suited for exterior installations and contact with treated lumber where corrosion risk is elevated
- Versatile across multiple structural applications - equally at home in floor-to-floor holdown assemblies and a wide range of other anchoring solutions, reducing the need to source multiple specialty products for a single project
- Domestic-quality steel construction - manufactured in the United States and built from steel, supporting consistent material quality and traceability for projects where documentation matters
