Professional Applications & Engineering Value
This 1/4"-28 UNF threaded rod delivers critical performance in high-stress environments where failure is not an option. Manufactured from ASTM Grade B7 steel, it provides exceptional resistance to elongation and structural fatigue under continuous load conditions. The fully threaded design offers unparalleled installation flexibility for piping systems, machinery anchoring, and structural frameworks. With its fine UNF threading and Class 2A thread fit, this rod ensures precise mating with corresponding nuts and components, minimizing the risk of loosening due to vibration or thermal cycling. The combination of 125,000 psi tensile strength and Rockwell C35 hardness makes it ideal for pressure vessel applications, chemical processing equipment, and heavy machinery where both mechanical strength and corrosion resistance are paramount.
Specification Summary & Compliance
This inch-system threaded rod features 1/4"-28 UNF fine threading with Class 2A external thread fit per unified screw thread standards. Manufacturing complies with ASTM A193 specification for high-temperature service alloy steel bolting materials. The product meets RoHS 3 (2015/863/EU) compliance for restricted hazardous substances and REACH (EC 1907/2006) compliance regarding chemical registration, evaluation, and authorization. Thread direction is standardized right-hand for universal compatibility with industrial fastening systems.
