Product Description
The Simpson ATR 7/8 in. x 12 in. Hot-Dip Galvanized All-Thread Rod by Simpson is a fully threaded tension transfer element engineered for reliable performance in structural anchoring applications. Designed to work with Simpson Strong-Tie adhesives, this all-thread rod delivers consistent load transfer in floor-to-floor holdown assemblies and a broad range of other anchoring solutions. Its hot-dip galvanized finish provides extra corrosion resistance, making it a dependable choice for exterior connections and treated-wood construction where moisture and chemical exposure are ongoing concerns.
Key Features
- Fully threaded along the entire length - maximizes versatility by allowing the rod to engage hardware at any point, supporting a wide range of anchoring configurations
- Cut to length for convenience - thread runs the full length, so the rod can be trimmed on-site without sacrificing thread engagement or usability
- 7/8 in. diameter, 12 in. length - a robust size suited for structural holdown and anchoring applications requiring a strong, load-bearing threaded element
- Hot-dip galvanization (HDG) - offers extra corrosion resistance for exterior and treated-wood applications, outperforming standard zinc-plated finishes in harsh or high-moisture environments
- UNC Class 2A or 1A thread specifications - ensures compatibility with standard UNC-threaded hardware, fasteners, and nuts of the appropriate size and matching material and finish
- Designed for use with Simpson Strong-Tie adhesives - integrates directly into Simpson Strong-Tie anchoring systems for verified, system-level structural performance
Why This Product
- Built for demanding structural applications - as a tension transfer element engineered for floor-to-floor holdowns and structural anchoring, this threaded rod is purpose-designed for the load demands that general hardware simply is not rated to handle
- Hot-dip galvanized finish for long-term durability - the HDG coating delivers extra corrosion resistance compared to zinc plating, making this rod a practical choice for exterior installations and treated-wood environments where premature corrosion is a real risk
- Full-length threading eliminates positioning constraints - because every inch of the rod is threaded, it can be cut to a needed length on-site and still provide full thread engagement, giving contractors and builders greater flexibility during installation
- System-matched for Simpson Strong-Tie adhesive anchoring - the ATR rod is specifically designed to work within the Simpson Strong-Tie adhesive anchor system, helping ensure compatibility and performance confidence across the full assembly

Frequently Asked Questions
What makes hot-dip galvanization different from zinc plating on this all-thread rod?
Hot-dip galvanization (HDG) provides a thicker, more durable zinc coating compared to standard zinc plating. This extra corrosion resistance makes the HDG version particularly suitable for exterior applications and use with treated wood, where moisture and chemical exposure are greater concerns.
Is this all-thread rod fully threaded along its entire length?
Yes. The ATR7/8X12HDG is fully threaded along the entire length of the rod, which maximizes versatility and allows it to be used or cut to length at any point without losing thread engagement.
What thread specification does this rod follow?
This rod conforms to UNC Class 2A or 1A thread specifications, ensuring compatibility with standard UNC-threaded hardware and fasteners of the appropriate size and matching material and finish.
What adhesive system is this all-thread rod intended to be used with?
The ATR series all-thread rod is designed for use as a tension transfer element in conjunction with Simpson Strong-Tie adhesives, supporting structural applications such as floor-to-floor holdowns and various other anchoring solutions.
