Professional Applications & Engineering Value

This Grade 8 steel flange nut delivers critical engineering solutions where vibration resistance and load distribution are paramount. The integrated 3/4" flange acts as a built-in washer, eliminating the need for separate components while providing superior surface contact. The 3/8"-16 UNC coarse threads with Class 2B fit ensure reliable performance in high-stress environments such as heavy machinery, construction equipment, and automotive assemblies. The external hex drive design allows for standard tool compatibility, streamlining installation in confined spaces. Manufactured from high-grade steel, this heavy-duty flange nut maintains integrity under extreme tension and shear forces, making it ideal for structural applications requiring long-term fastening security.

Specification Summary & Compliance

This flange nut features 3/8"-16 UNC coarse threads with Class 2B thread fit for precision engagement. The standard external hex drive measures 9/16" across flats with an overall height of 11/32". The 3/4" diameter flange provides enhanced bearing surface with 0.08" thickness. Manufactured to meet Grade 8 strength classification and compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards for industrial applications.
