Product Description
The Simpson ATR 3/8 in. x 12 in. All-Thread Rod is a fully-threaded fastening rod from Simpson, engineered specifically for tension transfer in structural applications. Threaded continuously along its entire length, this rod delivers reliable engagement at any point, making it a practical choice for framing connections, anchor bolt setups, and other load-bearing assemblies where consistent thread coverage matters. Part of the ATR series, which spans diameters from 3/8 in. up to 2 in., this compact 3/8 in. diameter option suits projects where precision fit and full-length threading are essential.
Key Features
- Fully threaded along the entire length - allows the rod to be engaged, cut, or positioned at any point without losing thread coverage, maximizing installation flexibility
- Cut to length for convenience - arrives ready to trim to your exact project requirements, reducing on-site prep time
- Uncoated black steel construction - provides a straightforward, no-frills fastening element suited for interior structural applications where an additional coating is not required
- UNC Class 2A or 1A thread specifications - conforms to recognized thread standards, ensuring predictable compatibility with matching nuts and hardware that share the same material and finish
Why This Product
- Purpose-built for tension transfer - the ATR rod is specifically designed for tension transfer applications, meaning its threading and construction are selected with structural load demands in mind rather than general-purpose use
- Full-length threading removes guesswork - because the rod is threaded from end to end, installers can cut it to a custom length and still have complete thread access, reducing material waste and saving time on the job
- Standardized thread specification for reliable pairing - meeting UNC Class 2A or 1A thread specifications means this rod works predictably with compliant hardware, supporting consistent, repeatable connections across a project
- Made in the United States by a trusted structural hardware brand - Simpson produces this rod domestically, giving buyers confidence in sourcing and quality control for critical fastening applications
