Product Description
Simpson ATR 1 in. x 18 in. Hot-Dip Galvanized All-Thread Rod is a fully threaded steel tension transfer element from Simpson, engineered for use with Simpson Strong-Tie adhesives in demanding structural applications. Whether you are tackling floor-to-floor holdowns or a wide range of anchoring solutions, this all-thread rod delivers the threading consistency and corrosion protection needed to perform reliably in both interior framing and challenging exterior or treated-wood environments.
Key Features
- Fully threaded along the entire length of the rod - gives you maximum flexibility to cut the rod to the exact length your application requires, reducing waste and simplifying installation.
- Hot-dip galvanized finish - provides extra corrosion resistance compared to standard zinc-plated options, making this rod a dependable choice for exterior conditions and contact with treated wood.
- 1 in. diameter - delivers the load-bearing cross-section required for heavy-duty structural and anchoring applications.
- 18 in. length - offers a practical working length that accommodates common holdown and anchor bolt installations while remaining easy to handle on the job site.
- UNC Class 2A or 1A thread specifications - ensures compatibility with standard UNC-threaded nuts and connectors, simplifying hardware selection and assembly.
Why This Product
- Purpose-built for structural tension transfer - designed specifically as a tension transfer element for use with Simpson Strong-Tie adhesives, this all-thread rod integrates directly into engineered holdown and anchoring systems rather than serving as a generic fastener.
- Superior corrosion protection where it counts - the hot-dip galvanized coating is the right choice for exterior installations and treated-wood assemblies where moisture and chemical exposure can degrade lesser finishes over time.
- Cut-to-length versatility - full threading from end to end means the rod can be trimmed on site to fit the precise depth or height your project demands, without sacrificing thread engagement at the cut end.
- American-made steel construction - built from steel and produced domestically, this rod meets the material and quality expectations required for load-critical structural connections.
