Professional Applications & Engineering Value

This 3/4"-10 UNC threaded rod manufactured from ASTM Grade B7 steel delivers robust performance for heavy-duty fastening in industrial settings. The fully threaded configuration allows continuous engagement in structural assemblies, piping systems, and machinery frames where adjustable tension is critical. With its 125,000 psi tensile strength and Rockwell C35 hardness, it resists vibrational loosening and mechanical stress in high-temperature or corrosive environments. The coarse thread spacing and Class 2A thread fit ensure compatibility with standard components, reducing installation time while maintaining reliable fastening solutions for construction, oil and gas, and manufacturing applications.

Specification Summary & Compliance

This threaded rod features 3/4"-10 UNC coarse threads with Class 2A external thread fit per standard inch system tolerances. It complies with ASTM A193 Grade B7 manufacturing specifications for material and mechanical properties. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring environmental and safety standards for industrial use.
