Professional Applications & Engineering Value
This heavy-duty flange lock nut delivers critical vibration resistance in demanding industrial applications where secure fastening is paramount. The black-oxide steel construction provides durable corrosion protection while the integrated serrated locking mechanism creates positive locking action that maintains clamp load under extreme vibration conditions. The UNC coarse threads with Class 2B thread fit ensure reliable engagement with standard bolts, making these flange nuts ideal for machinery, structural steel connections, automotive assemblies, and heavy equipment where vibration-resistant fastening is essential. The built-in flange eliminates the need for separate washers, streamlining installation while providing superior bearing surface distribution.
Specification Summary & Compliance
This flange lock nut features 5/8"-11 UNC coarse threads with Class 2B thread fit for precise dimensional accuracy and reliable mating with standard bolts. The external hex drive measures 15/16" across flats with a 9/16" height profile. Manufacturing complies with industry standards for flange nuts including a 1 9/32" flange diameter and 0.05" flange thickness. The product is fully REACH (EC 1907/2006) compliant and meets RoHS 3 (2015/863/EU) requirements for environmental safety and restricted substances.
