Professional Applications & Engineering Value
This high-strength threaded rod solves critical engineering challenges in construction, machinery assembly, and structural applications where vibration resistance and long-term reliability are paramount. The combination of ASTM A354BD Grade BD steel and zinc yellow-chromate plating creates a durable fastening solution that withstands corrosive environments while maintaining 150,000 psi tensile strength. The 1/2"-20 UNF fine threads provide superior load distribution compared to coarse threads, making it ideal for precision equipment, automotive components, and industrial machinery requiring Class 2A thread fit tolerance. The fully threaded design allows for adjustable positioning throughout the entire 3" length, offering installation flexibility that partial-threaded alternatives cannot match.
Specification Summary & Compliance
This threaded rod maintains Class 2A thread fit tolerance per UNF standards with 1/2"-20 fine threading configuration. Manufactured to ASTM A354BD specifications with Rockwell C33 hardness and 150,000 psi tensile strength. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
