Professional Applications & Engineering Value

This 5/16"-24 UNF thin Flex-Top locknut delivers critical engineering solutions where vibration-induced loosening compromises assembly integrity. The 18-8 stainless steel construction provides exceptional corrosion resistance for demanding environments including marine, chemical processing, and outdoor equipment. The thin profile design addresses space-constrained applications while maintaining full locking performance through the Flex-Top technology that creates consistent friction along the thread engagement. The fine thread configuration (24 TPI) offers superior adjustment precision compared to coarse threads, making it ideal for precision machinery, automotive subsystems, and electronic enclosures where minute positional adjustments are critical. The external hex drive ensures compatibility with standard tools, streamlining installation in high-volume production environments.

Specification Summary & Compliance

This locknut features Class 2B thread fit per UNF standards, ensuring precise dimensional accuracy and reliable performance. The 5/16"-24 UNF fine thread specification provides optimal engagement characteristics for vibration-prone applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental compliance for global industrial use. The thin profile configuration (1/2" width × 17/64" height) maintains structural integrity while minimizing package size, meeting demanding space requirements without compromising locking performance.
