Professional Applications & Engineering Value

This Grade 8 black-oxide steel hex nut is engineered to address critical challenges in industrial fastening, where vibration resistance and long-term durability are paramount. The coarse UNC thread design prevents seizing in high-vibration environments common in construction equipment, mining machinery, and heavy transport applications. The black-oxide coating provides superior protection against rust and corrosion, making it ideal for outdoor installations or humid operating conditions. With its right-hand thread direction and standard hex profile, it ensures compatibility with existing industrial components while maintaining consistent torque performance. These features combine to deliver reliable fastener integrity in critical assemblies where failure is not an option.

Specification Summary & Compliance

This heavy-duty hex nut features 1 3/4"-5 UNC coarse threading with Class 2B thread fit for precise dimensional accuracy. Manufactured from high-strength black-oxide steel meeting Grade 8 mechanical properties, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The external hex drive configuration follows industry-standard specifications for compatibility with standard wrenching tools.
