Professional Applications & Engineering Value
Engineered for demanding industrial applications, this black-oxide steel flange nut delivers critical performance where vibration resistance and corrosion protection are paramount. The Class 3B thread fit maintains tight tolerances under dynamic loads, preventing costly downtime in machinery, heavy equipment, and structural assemblies. The integrated 31/32" flange distributes clamping force evenly, protecting soft materials and painted surfaces while the external 12-point drive accommodates high-torque requirements in confined spaces. This UNC coarse thread configuration ensures rapid assembly in manufacturing lines and maintenance operations, making it an ideal heavy-duty fastening solution for automotive, construction, and industrial machinery sectors.
Specification Summary & Compliance
Manufactured to precise inch system dimensions with Class 3B thread fit per UNC standards, ensuring consistent performance across applications. Features 9/16"-12 UNC coarse threads with right-hand direction and standard hex nut profile. The black-oxide surface treatment provides enhanced corrosion resistance while maintaining dimensional stability. Complies with industry standards for heavy-duty industrial fasteners and meets relevant material specifications for steel components.
