Professional Applications & Engineering Value
This black-oxide steel flange nut delivers critical engineering advantages where vibration resistance and load distribution are paramount. The integrated 1-3/8" steel flange eliminates the need for separate washers while providing superior surface contact, preventing material deformation in heavy machinery, structural steelwork, and automotive assemblies. The UNC coarse thread profile with Class 2B fit ensures rapid installation in high-volume production environments while maintaining consistent clamping force. The rotating performance property makes it ideal for applications requiring adjustment under load, while the external hex drive accommodates standard industrial tools for reliable torque application in confined spaces.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2B thread fit for consistent engagement and UNC coarse thread specifications (5/8"-11). The nut features a standard hex nut profile with 1-1/16" width and 29/32" height for uniform tool compatibility. Full compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations ensures suitability for regulated industrial applications across multiple sectors.
