Professional Applications & Engineering Value
This Grade 2 steel hex nut with 1 7/8"-12 UN extra fine thread addresses critical engineering challenges in heavy machinery, structural assemblies, and precision equipment. The thin profile design solves space constraints while maintaining full thread engagement, making it ideal for compact assemblies where standard nuts won't fit. The extra fine thread spacing provides superior resistance to vibration loosening, a common failure point in industrial equipment. Manufactured from steel with external hex drive, this nut ensures reliable performance in applications requiring repeated maintenance access. The Class 2B thread fit guarantees consistent installation torque values, crucial for quality control in manufacturing and assembly operations.
Specification Summary & Compliance
This hex nut features 1 7/8"-12 UN extra fine threads with Class 2B thread fit per UN standards, ensuring precise dimensional accuracy. The thin profile measures 2 13/16" across flats and 1 1/32" in height. Manufactured from Grade 2 steel with right-hand thread direction and external hex drive. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards for industrial use.
