Key Features & Benefits at a Glance

  • Exceptional tensile strength of 125,000 PSI provides reliable load-bearing capacity for demanding industrial applications.
  • High hardness rating (Rockwell C35) ensures superior wear resistance and long-term durability under stress.
  • Full-length threading offers versatile installation and adjustment flexibility across the entire 6-foot length.
  • Precision Class 2A thread fit guarantees smooth assembly and secure fastening with compatible nuts.
  • ASTM Grade B7 material compliance delivers consistent performance in high-temperature and high-pressure environments.
  • RoHS 3 compliance ensures environmental safety and meets strict regulatory standards for hazardous substances.
  • UN fine thread design provides improved vibration resistance and finer adjustment control in machinery.

Professional Applications & Engineering Value

This 1 5/8"-8 threaded rod manufactured from ASTM Grade B7 steel addresses critical engineering challenges in heavy-duty applications. The fully threaded design with UN fine threads enables precise tension control and uniform stress distribution, preventing joint failure in structural assemblies. With its 125,000 PSI tensile strength and Rockwell C35 hardness, it solves vibration-induced loosening problems in industrial machinery, construction frameworks, and pressure vessel systems. The right-hand thread direction ensures compatibility with standard fastening components while the 6-foot length provides installation flexibility for large-scale projects requiring extended threaded connections.

Specification Summary & Compliance

This threaded rod maintains Class 2A thread fit tolerances per UN standards with 1 5/8"-8 fine threading. Manufactured to ASTM A193 specifications for high-temperature service, it meets ASTM Grade B7 mechanical properties including 125,000 PSI tensile strength and Rockwell C35 hardness. Compliant with RoHS 3 (2015/863/EU) environmental regulations for hazardous substance restrictions.
