Professional Applications & Engineering Value
This black-oxide steel flange lock nut combines distorted thread locking technology with a 9/16" flange diameter to solve critical vibration and load distribution challenges in industrial assemblies. The Grade G strength classification ensures structural integrity in heavy machinery, automotive, and construction applications where constant stress would compromise standard fasteners. The UNC coarse thread design enables rapid installation in high-volume production environments while maintaining Class 2B thread fit precision. The integrated flange eliminates the need for separate washers, reducing component count and assembly time while providing superior bearing surface protection. This engineered solution delivers reliable performance in vibration-prone equipment, transportation systems, and industrial machinery where safety-critical connections demand zero compromise.
Specification Summary & Compliance
This 1/4"-20 flange lock nut features UNC coarse threading with Class 2B thread fit tolerance for precise engagement. Manufactured from black-oxide steel with Grade G strength classification, the nut includes a 9/16" flange diameter and 7/16" width with external hex drive. The product complies with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring environmental responsibility and global market acceptance for industrial fastener applications.
