Professional Applications & Engineering Value

This Grade 8 black-oxide steel flange lock nut delivers critical vibration resistance in demanding industrial applications where secure fastening is paramount. The serrated locking mechanism creates permanent resistance to rotational loosening, making it ideal for machinery, automotive assemblies, and structural frameworks subject to constant vibration and shock loads. The integrated flange provides superior load distribution, reducing surface pressure and preventing damage to connected components. Manufactured from high-strength steel with black-oxide surface treatment, this nut maintains performance in corrosive environments while the UNC coarse threads ensure quick assembly and disassembly. Engineered for heavy equipment, construction machinery, and transportation applications where reliability cannot be compromised.

Specification Summary & Compliance

This flange lock nut features 1/2"-13 UNC coarse threads with Class 2B thread fit for precision engagement and consistent performance. The right-hand thread direction follows industry standards for compatibility with common fastening systems. Manufacturing complies with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring environmental compliance for industrial use. The Grade 8 strength classification guarantees high tensile strength and reliable performance in critical applications, while the external hex drive design maintains compatibility with standard tooling systems.
