Product Description
The Simpson ATR 3/4 in. x 18 in. Zinc-Plated All-Thread Rod is a fully threaded tension transfer element from Simpson, engineered for use with Simpson Strong-Tie adhesives in demanding structural applications. Fully threaded along its entire length, this zinc-plated steel rod delivers the versatility contractors and builders need for floor-to-floor holdown systems and a wide range of anchoring solutions where reliable load transfer is critical.
Key Features
- Fully threaded along the entire length - threads from end to end allow flexible positioning, cutting, and securing without dead zones, so you can adapt the rod to your exact installation needs
- Cut to length for convenience - the full-thread design means the rod can be trimmed on site without losing thread coverage, reducing material waste and saving installation time
- 3/4 in. diameter x 18 in. length - a robust, purpose-matched size suited for structural tension transfer in holdown and anchoring applications
- Zinc-plated steel construction - the zinc-plated finish over steel provides a protective coating appropriate for the structural and anchoring applications in which this rod is designed to be used
- UNC Class 2A or 1A thread specifications - conforms to standard unified coarse thread classifications, ensuring compatibility with hardware designed for those thread classes
Why This Product
- Designed for Simpson Strong-Tie adhesive systems - this rod is purpose-built as a tension transfer element for use with Simpson Strong-Tie adhesives, making it a natural fit for anchoring and holdown assemblies that rely on that bonding system
- Maximum installation flexibility - because the rod is threaded along its full 18 in. length, it can be cut to any required dimension on the job site without sacrificing thread engagement or performance
- Versatile across multiple structural applications - from floor-to-floor holdowns to a wide range of other anchoring solutions, a single rod handles diverse fastening demands, reducing the need to stock multiple specialty components
