Key Features & Benefits at a Glance

  • Exceptional load-bearing capacity with 125,000 psi tensile strength for reliable performance in demanding applications
  • Superior durability and wear resistance thanks to Rockwell C35 hardness and ASTM Grade B7 steel construction
  • Optimal load distribution achieved through full threading along the entire 2-foot length
  • Precise and reliable fastening ensured by Class 2A thread fit and UNC coarse thread profile
  • Enhanced compatibility with standard components using right-hand thread direction and 1 3/8"-6 thread size
  • Regulatory compliance assurance meeting ASTM A193 specifications and environmental standards including RoHS 3 and REACH
  • Reduced installation time through coarse threading that enables faster assembly compared to fine threads

Professional Applications & Engineering Value

This high-strength threaded rod delivers exceptional engineering value in heavy-duty industrial applications where failure is not an option. The ASTM Grade B7 steel construction provides outstanding resistance to stress and temperature variations, making it ideal for pressure vessel systems, structural supports, and machinery assemblies. The fully threaded design allows for adjustable positioning and uniform stress distribution along the entire length, eliminating weak points common in partially threaded alternatives. With UNC coarse threading and Class 2A thread fit, this rod ensures quick installation and reliable engagement in high-vibration environments. The combination of 125,000 psi tensile strength and Rockwell C35 hardness makes this threaded rod particularly valuable in construction, oil and gas, and manufacturing sectors where heavy duty fasteners must withstand extreme mechanical loads and environmental challenges.

Specification Summary & Compliance

This threaded rod maintains precise Class 2A thread fit tolerances according to UNC thread standards with 1 3/8"-6 coarse thread spacing. Manufactured to ASTM A193 specifications for high-temperature service, the product carries ASTM Grade B7 classification with verified mechanical properties including 125,000 psi tensile strength and Rockwell C35 hardness. The rod is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting current environmental regulations for industrial components.
