Product Description
The Simpson ATR 1/2 in. x 12 in. Zinc-Plated All-Thread Rod from Simpson is a fully threaded tension transfer element engineered for use with Simpson Strong-Tie adhesives. Constructed from zinc-plated steel and threaded along its entire length, this all-thread rod delivers versatile performance across structural anchoring applications - from floor-to-floor holdown assemblies to a wide range of adhesive-based anchoring solutions where precise positioning and reliable load transfer are essential.
Key Features
- Fully threaded along the entire length - allows nuts, couplers, and structural hardware to be positioned anywhere along the rod, maximizing installation flexibility.
- 1/2 in. diameter - a widely used structural size that pairs with standard hardware, anchors, and holdown components without special adapters.
- 12 in. length, cut to length for convenience - provides a ready-to-use rod that can be trimmed on-site to fit the exact requirements of your application.
- Zinc-plated steel construction - offers a corrosion-resistant finish suited for interior structural applications and assembly use with Simpson Strong-Tie adhesives.
- UNC Class 2A or 1A thread specifications - conforms to standard unified coarse thread classifications, ensuring compatibility with common structural nuts and threaded hardware used in anchoring assemblies.
Why This Product
- Engineered for adhesive anchor systems - designed specifically as a tension transfer element for use with Simpson Strong-Tie adhesives, making it a purposeful choice for structural anchoring work rather than a generic threaded rod.
- Unrestricted positioning along the full thread - because the rod is threaded from end to end, installers can adjust bearing points, couplers, and fasteners anywhere along the 12 in. length, reducing waste and re-work on the job site.
- Domestic origin with a recognized structural brand - produced in the United States and backed by Simpson, a name widely specified in structural hardware for holdowns and anchoring applications.
- Available in zinc-plated finish - the zinc-plated coating provides a corrosion-resistant surface for interior and sheltered structural applications, with hot-dipped galvanized options also available from Simpson for more demanding environments.
