Professional Applications & Engineering Value
This Grade 5 hex nut delivers critical engineering solutions where high tensile strength and durable fastening are paramount. The black oxide steel construction provides essential corrosion protection for industrial equipment, construction machinery, and structural applications exposed to demanding conditions. The 1"-8 UNC coarse thread configuration offers significant advantages in assembly speed and debris resistance compared to fine-thread alternatives, while the Class 2B thread fit maintains precise tolerances for consistent clamping force distribution. Engineered to ASME B18.2.2 standards, this external drive hex nut ensures reliable performance in heavy-duty bolted connections where vibration resistance and long-term integrity are critical requirements.
Specification Summary & Compliance
This hex nut features 1"-8 UNC coarse threads with Class 2B thread fit per standard inch-series tolerances. Manufacturing complies with ASME B18.2.2 specifications for dimensional accuracy and mechanical properties. The fastener meets Grade 5 strength classification requirements and demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Physical dimensions include 1-1/2" width across flats and 55/64" height, with right-hand thread direction for standard applications.
