Professional Applications & Engineering Value

This Grade 8 flange nut delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The 1 1/32" flange diameter provides enhanced bearing surface that distributes clamping force effectively, preventing surface damage and maintaining joint integrity under dynamic loads. The 1/2"-13 UNC coarse thread configuration offers superior engagement in materials where fine threads might strip or fail, making it ideal for heavy machinery, construction equipment, and automotive assemblies. Manufactured from high-strength steel with external hex drive, this fastener withstands extreme torque requirements while maintaining its mechanical properties. The combination of Class 2B thread fit and robust construction addresses common industrial challenges including joint relaxation, material fatigue, and environmental degradation.

Specification Summary & Compliance

This heavy-duty flange nut features precision 1/2"-13 UNC coarse threads with Class 2B thread fit tolerance for consistent mating performance. The standard external hex drive (3/4" width) accommodates common industrial tools, while the integrated flange measures 1 1/32" in diameter with 0.1" thickness for optimal load distribution. Manufactured to meet Grade 8 strength requirements and compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, ensuring both mechanical reliability and regulatory adherence for industrial applications.
