Product Description
The Simpson ATR 1-1/8 in. x 24 in. All-Thread Rod is a fully threaded fastening rod from Simpson engineered specifically for tension transfer applications. Threaded from end to end, it delivers consistent engagement at any point along its length, making it a reliable choice for structural connections and a wide range of installation scenarios. The ATR series spans diameters from 3/8 in. up to 2 in., giving builders and contractors a scalable family of rods to match varying load and project requirements.
Key Features
- Fully threaded along the entire length - allows fastening, anchoring, or coupling at any point on the rod without repositioning or special placement
- Cut to length for convenience - arrives ready to use at a practical 24 in. length, reducing prep time and on-site fabrication effort
- Uncoated black steel construction - provides solid structural integrity in a straightforward, no-frills finish suited to interior and dry-environment applications
- UNC Class 2A or 1A thread specifications - conforms to standard Unified National Coarse thread tolerances, ensuring broad compatibility with matching nuts and hardware
- 1 1/8 in. diameter - delivers the cross-sectional strength needed for heavy-duty tension transfer connections where smaller rods would be undersized
Why This Product
- Purpose-built for tension transfer - unlike general-purpose threaded rod, the ATR is specifically designed by Simpson for tension transfer applications, so structural performance is the priority from the ground up
- Full-length threading maximizes installation flexibility - because every inch of the rod is threaded, it can be cut, adjusted, or connected at any point, reducing waste and adapting easily to varying field conditions
- Domestic production - made in the United States, supporting consistent quality standards and reliable material sourcing
- Part of a broad diameter range - the ATR family runs from 3/8 in. through 2 in. in diameter, so this rod fits naturally into multi-fastener projects where different sizes are needed across the same system
