Professional Applications & Engineering Value

This 5/16"-18 UNC fully threaded steel rod addresses critical engineering challenges in industrial fastening systems where vibration resistance and consistent performance are paramount. The Class 1A thread fit provides necessary clearance for rapid assembly in manufacturing environments while maintaining secure connections. The coarse UNC threading proves particularly valuable in applications where debris accumulation might compromise finer threads, making it ideal for construction equipment, machinery frames, and structural supports. With its 50,000 psi tensile strength and Rockwell B61 hardness, this threaded rod maintains dimensional stability under heavy loads, preventing thread stripping and connection failure in dynamic industrial settings. The right-hand threading direction follows conventional installation practices, reducing operator error and training requirements.

Specification Summary & Compliance

This inch-system threaded rod features 5/16"-18 UNC coarse threading with Class 1A external thread fit per ASME B1.1 standards, ensuring proper clearance for commercial applications. The 7/8" length maintains precise dimensional tolerances throughout the fully threaded design. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety standards for industrial components. The specified 50,000 psi tensile strength and Rockwell B61 hardness provide verified mechanical properties for engineering calculations and application specifications.
