Professional Applications & Engineering Value

These Grade 5 zinc plated steel hex nuts deliver exceptional engineering value in heavy machinery, structural steelwork, and industrial equipment applications. The coarse UNC thread design prevents binding during assembly while maintaining vibration resistance in high-stress environments. The zinc plating provides sacrificial protection against corrosion, significantly extending service life in outdoor or chemically aggressive settings. With 2"-4 1/2" thread sizes available, these ASME B18.2.2 compliant fasteners solve critical challenges in construction, manufacturing, and infrastructure projects where reliable fastening solutions must withstand extreme loads and environmental exposure without compromising performance.

Specification Summary & Compliance

Manufactured to ASME B18.2.2 standards with Class 2B thread fit tolerances for precision engagement. Features UNC coarse threads in right-hand direction with sizes ranging from 2" to 4 1/2". Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The Grade 5 strength classification ensures consistent mechanical performance across all applications.
