The Simpson ATR 5/8 in. x 12 in. Hot-Dip Galvanized All-Thread Rod is a fully threaded tension transfer element engineered for use with Simpson adhesives in demanding structural applications. Fully threaded along its entire length, this all-thread rod delivers the versatility needed for floor-to-floor holdown assemblies and a wide range of anchoring configurations. Its hot-dip galvanized finish provides extra corrosion resistance, making it a dependable choice for exterior environments and construction involving treated wood.

Key Features

• Fully threaded along the entire length - gives you maximum flexibility to cut the rod to the exact length your application requires, reducing waste and saving time on site.
• 5/8 in. diameter, 12 in. length - a practical mid-range size that covers common holdown and structural anchoring needs without requiring custom hardware.
• Hot-dip galvanized finish - delivers extra corrosion resistance compared to standard zinc-plated rods, making this threaded rod well suited for exterior installations and treated-wood construction environments.
• UNC Class 2A or 1A thread specifications - ensures compatibility with standard UNC-threaded nuts and hardware, simplifying hardware selection and reducing the risk of mismatched components.
• Designed as a tension transfer element for use with Simpson adhesives - provides a system-ready anchoring solution engineered to work within proven structural assemblies, including floor-to-floor holdowns.

Why This Product

• Built for corrosive environments - the hot-dip galvanized coating goes beyond basic zinc plating to protect the steel rod against moisture and the chemicals present in treated-wood applications, extending service life in conditions where standard rods fall short.
• Versatile by design - because this all-thread rod is fully threaded and easy to cut to length, a single rod can serve multiple anchoring configurations, from floor-to-floor holdown assemblies to a wide variety of structural tie applications.
• System-engineered compatibility - as part of the Simpson lineup of tension transfer elements, this rod is designed specifically for use with Simpson adhesives, giving contractors confidence in load-path integrity across the full anchoring assembly.
• Domestically produced steel construction - made in the United States from steel, offering consistent material quality that professional builders and engineers can rely on for structural applications.
