Professional Applications & Engineering Value

This 3/8"-24 UNF steel locknut delivers exceptional engineering value through its two-piece clamp locking mechanism that effectively counters vibrational loosening in demanding industrial applications. The fine thread configuration provides superior load distribution across more thread contact points, while the Class 2B thread fit ensures precise mating with mating components without binding. The external hex drive design allows for high torque application in confined spaces, making it ideal for machinery assembly, automotive systems, and heavy equipment where vibration resistance and reliable fastening are critical. Manufactured from high-grade steel with standardized dimensions, this locknut maintains structural integrity under repeated stress cycles while offering easy installation with common tools.

Specification Summary & Compliance

This locknut features Class 2B thread fit per UNF standards with precise 3/8"-24 fine thread specifications. The external hex drive measures 9/16" across flats with a 33/64" height profile. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety standards. The right-hand thread direction and standard hex nut profile maintain compatibility with industry-standard installation tools and procedures.
