• Exceptional corrosion protection from zinc-flake coating that withstands harsh industrial environments
• Precise thread engagement with Class 2B fit ensuring reliable performance in fine-thread applications
• Optimized installation efficiency through standard external hex drive compatible with common tools
• Long-term reliability in heavy-duty applications due to robust steel construction
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial use

Professional Applications & Engineering Value

This zinc-flake-coated steel flange locknut delivers critical vibration resistance in demanding applications where UNF fine threads and secure fastening are essential. The 3/4" flange diameter significantly increases bearing surface area, distributing clamp load effectively to prevent joint loosening in heavy machinery, automotive assemblies, and industrial equipment. The serrated locking mechanism bites into mating surfaces, creating permanent resistance to rotational forces that cause conventional nuts to fail. Manufactured with Class 2B thread fit, this external hex flange nut ensures precise engagement with mating bolts while the corrosion-resistant zinc-flake coating provides durable protection in challenging environments where reliability cannot be compromised.

Specification Summary & Compliance

This 3/8"-24 UNF flange locknut features Class 2B thread fit for precision engagement with standard UNF fasteners. The external hex drive (9/16" width) and standard hex nut profile ensure compatibility with common installation tools. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental compliance for industrial applications worldwide. The fine thread spacing (24 TPI) and right-hand thread direction follow established industrial standards for reliable performance in vibration-prone applications.
