• Reliable thread engagement with Class 2B fit ensures consistent clamping force and vibration resistance
• Quick installation using standard 3/4" external hex drive compatible with common industrial tools
• Robust coarse threading (7/16"-14 UNC) provides excellent resistance to cross-threading and debris accumulation
• Environmental compliance meeting RoHS 3 standards for responsible manufacturing and global acceptance
• Optimized flange design combining 0.16" thickness with standard hex profile for balanced strength and accessibility

Professional Applications & Engineering Value

Engineered for demanding industrial fastening applications, this black-oxide steel flange nut solves critical challenges in assembly operations where vibration resistance and corrosion protection are paramount. The integrated flange design eliminates washer requirements while providing superior bearing surface distribution, making it ideal for automotive chassis, heavy machinery, and structural frameworks. The UNC coarse thread configuration ensures rapid assembly in high-volume production environments while maintaining Class 2B thread fit precision for consistent torque performance. The black-oxide surface treatment creates a durable barrier against moisture and chemical exposure, significantly extending maintenance intervals in outdoor equipment and manufacturing facilities where environmental factors compromise fastener integrity.

Specification Summary & Compliance

Manufactured to precise inch system specifications with Class 2B thread fit tolerance ensuring compatibility with standard UNC threaded components. The 7/16"-14 coarse thread follows Unified National Coarse standards while the external hex drive (3/4" width) provides reliable tool engagement. Full compliance with RoHS 3 (2015/863/EU) regulations under exemption 6(a) for lead as steel alloying element, meeting international environmental standards for industrial components.
