Product Description
The Simpson Strong-Tie ATR All-Thread Rod 1-1/8 in. x 12 in. is a fully threaded steel rod engineered to serve as the tension transfer element within Simpson Strong-Tie's Strong-Rod systems. Built for demanding structural applications, this uncoated black steel rod is approved for use in both the Anchor Tiedown System for shearwall overturning restraint and the wind uplift restraint system, making it a purpose-built component for contractors and builders working on code-compliant lateral and uplift force resistance.
Key Features
- Full thread along the entire length - allows flexible positioning and adjustment during installation, so the rod can be cut or connected at virtually any point without losing thread engagement
- Approved for use in the Anchor Tiedown System for shearwall overturning restraint - gives builders a verified tension transfer component for resisting the lateral forces that act on shearwalls during seismic or wind events
- Compatible with the wind uplift restraint system - provides a single rod solution that works across both overturning and uplift restraint applications, reducing the need for multiple product types on the same job
- Uncoated black steel construction - meets the material specification required for use within Simpson Strong-Tie's rod-based restraint systems, ensuring proper compatibility with approved system hardware
- Nut material and finish must match the rod - a critical pairing requirement that ensures nuts seat and thread correctly, preventing installation errors that could compromise structural performance
Why This Product
- System-specific engineering - this rod is designed from the ground up as the tension transfer element within Simpson Strong-Tie's Strong-Rod systems, meaning it is not a generic threaded rod adapted for structural use but a purpose-engineered component built for these applications
- Dual-application approval - approval for both shearwall overturning restraint and wind uplift restraint means this single rod can address two distinct structural challenges on the same project, simplifying procurement and inventory
- Full-length threading maximizes installation flexibility - contractors can position connections anywhere along the rod's length, accommodating varying field conditions without requiring custom-cut or special-length components
- Defined material specification supports code-compliant assemblies - the uncoated black steel designation ensures this rod matches the material and finish requirements of the system hardware it pairs with, supporting proper load transfer and inspection-ready installations

Frequently Asked Questions
What systems is this all-thread rod designed to be used with?
This fully threaded rod is designed for use within both the Simpson Strong-Tie Anchor Tiedown System for shearwall overturning restraint (ATS) and the wind uplift restraint (URS) system, where it functions as the tension transfer element.
What are the dimensions of the ATR1-1/8X12?
The ATR1-1/8X12 has a diameter of 1-1/8 inches and a length of 12 inches.
What material and finish is this threaded rod made from?
This all-thread rod is made from uncoated black steel, making it suitable for structural applications where this material specification is required.
Do I need to match the nut material and finish to this rod?
Yes. When pairing a nut with this threaded rod, the material and finish must match. If the material and finish do not match, the nut will not fit the rod properly.
