Professional Applications & Engineering Value

This Grade 8 flange nut delivers exceptional engineering value through its zinc-plated steel construction and integrated flange design. The 3/8"-16 UNC coarse threads provide rapid installation in high-volume assembly operations while maintaining vibration resistance. The 3/4" flange diameter creates a wider bearing surface that prevents loosening under dynamic loads and protects softer materials from damage. The external hex drive ensures compatibility with standard industrial tools, streamlining maintenance procedures. Ideal for heavy machinery, structural steel connections, and automotive applications, this heavy-duty hex nut solves common challenges of joint integrity, corrosion protection, and assembly efficiency in demanding industrial environments.

Specification Summary & Compliance

This flange nut features 3/8"-16 UNC coarse threads with Class 2B thread fit for precise dimensional accuracy and reliable mating. The standard hex nut profile with 9/16" width and 11/32" height ensures proper wrench engagement. Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, while the Grade 8 strength classification confirms mechanical performance meets industrial requirements for high-strength fastening applications.
