Professional Applications & Engineering Value

This high-strength threaded rod delivers exceptional engineering value in demanding industrial environments where fastener failure is not an option. The ASTM Grade B7 steel construction provides superior resistance to creep and relaxation under sustained loads, making it ideal for pressure vessel applications, structural supports, and heavy machinery assemblies. The fully threaded design with 5/8"-18 UNF fine threading offers maximum engagement surface area, distributing stress evenly and preventing thread stripping in high-vibration applications. With its Class 2A thread fit, this rod ensures precise mating with corresponding nuts and components, reducing installation time and minimizing the risk of cross-threading in production environments. The combination of 125,000 psi tensile strength and Rockwell C35 hardness provides the perfect balance of strength and machinability for critical fastening applications across multiple industries.

Specification Summary & Compliance

This threaded rod meets ASTM A193 specifications for high-temperature service and maintains dimensional accuracy with Class 2A thread fit per UNF standards. The 5/8"-18 fine thread spacing ensures precise engagement while the fully threaded, right-hand configuration provides consistent performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility and global market acceptance for industrial applications requiring verified material safety and performance standards.
