Professional Applications & Engineering Value
This Grade G flange lock nut addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and heavy equipment. The distorted thread locking technology creates consistent friction along the 3/8"-24 UNF fine threads, eliminating the need for secondary locking devices while maintaining Class 2B thread precision. The black-phosphate steel construction provides durable corrosion resistance in harsh environments, while the integrated 13/16" flange distributes clamping force over a wider area, preventing surface damage to connected components. This combination of vibration-resistant locking and enhanced load distribution makes it ideal for permanent installations where maintenance access is limited and reliability is paramount.
Specification Summary & Compliance
This flange lock nut features 3/8"-24 UNF fine threads with Class 2B thread fit for precise engagement and consistent performance. Manufactured from black-phosphate steel to Grade G strength specifications, it includes a 13/16" flange diameter with 0.06" thickness and standard hex drive profile. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, ensuring suitability for regulated industrial applications worldwide.
