• Superior corrosion protection with black-phosphate steel coating, extending service life in demanding industrial conditions
• Heavy-duty load capacity meeting Grade 8 strength standards, ensuring reliable performance under extreme mechanical stress
• Quick and secure installation with UNC coarse threading and Class 2B fit, providing smooth engagement and consistent clamping force
• Enhanced torque application through standard external hex drive design, allowing for efficient tightening with common tools
• Regulatory compliance assurance with REACH and RoHS 3 certifications, meeting international safety and environmental standards
• Optimized flange dimensions (1 1/2" diameter, 0.16" thickness) distributing load effectively and preventing surface damage

Professional Applications & Engineering Value

This Grade 8 Black-Phosphate Steel Flange Nut addresses critical challenges in heavy machinery, construction equipment, and structural assemblies where vibration-induced loosening and corrosion compromise joint integrity. The UNC coarse thread configuration ensures rapid assembly in field conditions while maintaining Class 2B thread fit precision for consistent clamping performance. The integrated flange design provides superior bearing surface distribution, preventing embedment in softer materials and reducing maintenance frequency. Engineered for industrial applications requiring both mechanical strength and environmental resistance, the black-phosphate surface treatment creates a protective barrier against moisture and chemical exposure, making it ideal for outdoor equipment, automotive systems, and manufacturing infrastructure where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2B thread fit tolerance for optimal engagement with mating components. The 3/4"-10 UNC coarse thread follows standardized threading specifications ensuring interchangeability. Full compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations guarantees adherence to international substance restriction protocols. The Grade 8 strength classification confirms mechanical properties exceeding 150,000 PSI minimum tensile strength, making this flange nut suitable for critical applications requiring certified performance standards.
