- Superior corrosion resistance with black-oxide steel finish for extended service life in harsh industrial environments
- Enhanced load distribution through 19/32" flange diameter prevents surface damage and maintains joint integrity
- Precision fine threading with Class 3B fit ensures vibration-resistant, leak-proof connections in critical applications
- High-torque capability via external 12-point drive allows for secure installation in confined spaces
- Reliable right-hand UNF threading provides consistent performance across standardized industrial equipment
- Optimized flange thickness (0.13") balances strength with material efficiency for weight-sensitive assemblies
- Standard hex profile compatibility with common wrench sizes simplifies maintenance and replacement procedures
Professional Applications & Engineering Value
This black-oxide steel flange nut delivers exceptional engineering value where vibration resistance and corrosion protection are paramount. The 7/16"-20 UNF fine thread configuration with Class 3B precision creates secure, leak-resistant joints in hydraulic systems, pneumatic equipment, and automotive assemblies. The integrated 19/32" flange eliminates need for separate washers while distributing clamp load effectively across softer materials. The external 12-point drive enables high-torque installation in confined engine compartments and machinery frames, making it ideal for heavy-duty industrial fastening applications requiring reliable, maintenance-free performance.
Specification Summary & Compliance
Manufactured to UNF thread standards with Class 3B thread fit for precision tolerance, this flange nut features right-hand fine threading (20 TPI) and standard hex profile. The black-oxide surface treatment provides corrosion resistance while maintaining dimensional stability. Complies with industry standards for heavy-duty fasteners and meets material specifications for industrial applications requiring consistent performance under demanding conditions.
