Professional Applications & Engineering Value

This high-strength threaded rod solves critical engineering challenges in industrial settings where standard fasteners fail. The ASTM Grade B7 steel composition, combined with 7/8"-9 UNC coarse threading, provides exceptional resistance to vibration loosening and mechanical stress in heavy machinery, structural frameworks, and pressure boundary systems. The fully threaded design allows for adjustable positioning and maximum thread engagement in flanged connections, pipe supports, and anchor systems. With 125,000 psi tensile strength and Rockwell C35 hardness, this rod maintains performance integrity in elevated temperature environments common in petrochemical, power generation, and industrial processing applications where material creep and relaxation are primary concerns.

Specification Summary & Compliance

This threaded rod features precision Class 2A thread fit with 7/8"-9 UNC coarse thread spacing and right-hand thread direction. Manufacturing complies with ASTM A193 specification for Grade B7 alloy steel fasteners, ensuring consistent material properties and dimensional accuracy. The product meets industry standards for high-temperature service and is suitable for pressure vessel, valve, and flange applications where reliable threaded rod performance is essential.
