Product Description
The Simpson ATR 7/8 in. x 18 in. Hot-Dip Galvanized All-Thread Rod is a fully threaded tension transfer element from Simpson, engineered for use with Simpson Strong-Tie adhesives in demanding structural anchoring applications. Fully threaded along its entire length, this all-thread rod delivers the positioning flexibility needed for floor-to-floor holdowns and a wide range of other anchoring solutions. Its hot-dip galvanized finish provides extra corrosion resistance, making it a dependable choice for exterior environments and applications involving treated wood.
Key Features
- Fully threaded along the entire length - allows nuts, connectors, and anchoring hardware to be positioned anywhere on the rod, maximizing layout flexibility on the job site
- Cut to length for convenience - simplifies installation by letting you trim the rod to fit your specific application without special tooling or sourcing a custom length
- 7/8 in. diameter, 18 in. length - a robust sizing suited to structural holdown and anchoring applications where load transfer demands a larger-diameter threaded rod
- Hot-dip galvanized (HDG) finish - delivers extra corrosion resistance compared to standard zinc-plated options, making this rod the right call for exterior installations and contact with treated lumber
- UNC Class 2A or 1A thread specifications - ensures compatibility with standard UNC-threaded nuts and connectors, so pairing hardware to this rod is straightforward and reliable
- Steel construction - provides the strength and durability required for structural tension transfer in anchoring systems
Why This Product
- Built for structural anchoring with adhesive systems - designed specifically as a tension transfer element for use with Simpson Strong-Tie adhesives, this all-thread rod integrates directly into proven anchoring solutions including floor-to-floor holdowns rather than serving as a generic fastener
- Hot-dip galvanization goes beyond basic corrosion protection - where zinc-plated rods may fall short in wet or chemically active environments, the HDG finish on this rod handles exterior conditions and treated-wood contact, reducing the risk of premature corrosion and fastener failure
- Full-length threading eliminates positioning guesswork - because every inch of the rod is threaded, installers are not locked into fixed engagement zones, giving crews on-site flexibility when depth or connector placement needs to be adjusted
- Domestic production and consistent thread standards - made in the United States and conforming to UNC Class 2A or 1A thread specifications, this rod pairs predictably with standard hardware, cutting down on compatibility concerns during installation
