Product Description
The Simpson ATR 1 in. x 24 in. Hot-Dip Galvanized All-Thread Rod is a fully threaded steel tension transfer element built for use with Simpson adhesives in demanding structural applications. Whether you are tackling floor-to-floor holdowns or a broad range of anchoring solutions, this all-thread rod delivers the versatility and corrosion protection that structural work requires. The hot-dip galvanized finish makes it a reliable choice for exterior environments and applications involving treated wood, while full-length threading keeps your options open when cutting to a precise fit on the job site.
Key Features
- Fully threaded along the entire length - gives you the freedom to cut the rod to any required length without losing thread coverage, reducing waste and saving time on site.
- Hot-dip galvanized finish - provides extra corrosion resistance compared to standard zinc-plated options, making this rod well suited for exterior installations and contact with treated wood.
- 1 in. diameter - meets the structural demands of heavy-duty tension transfer and anchoring applications where a robust cross-section is required.
- 24 in. length - offers a practical working length for floor-to-floor holdowns and a wide variety of anchoring configurations before any field cutting.
- UNC Class 2A or 1A thread specifications - ensures compatibility with standard UNC hardware and predictable, code-consistent performance in structural assemblies.
- Designed for use with Simpson adhesives - engineered to work as a matched system with Simpson Strong-Tie adhesive anchoring products, supporting reliable load transfer at the connection point.
Why This Product
- Corrosion resistance where it counts - the hot-dip galvanized coating delivers a thicker, more durable protective layer than zinc plating, making this threaded rod a dependable choice for exterior structural connections and treated-lumber framing.
- Maximum on-site flexibility - because the rod is threaded from end to end, it can be cut to the exact length your application demands without any loss of usable thread, cutting down on material costs and field adjustments.
- Purpose-built for adhesive anchoring systems - the ATR is specifically designed as a tension transfer element for use with Simpson Strong-Tie adhesives, so it integrates directly into proven holdown and structural anchoring assemblies rather than serving as a generic substitute.
- Domestic steel construction - the rod is produced in the United States from steel, supporting consistent material quality for structural applications where performance predictability matters.
