Professional Applications & Engineering Value

This heavy-duty brass hex nut delivers critical engineering advantages in demanding industrial applications where corrosion resistance and reliability are paramount. The extra wide profile distributes clamping forces over a larger surface area, preventing material deformation in soft substrates and reducing maintenance frequency. The UNC coarse threads excel in high-vibration environments, maintaining secure fastening in machinery, structural assemblies, and heavy equipment. Manufactured from copper alloy brass, this nut provides excellent conductivity for electrical grounding applications while offering superior resistance to seawater, chemicals, and atmospheric corrosion compared to steel alternatives. The Class 2B thread fit ensures consistent performance with standard bolts, streamlining inventory management and installation processes across industrial maintenance and manufacturing operations.

Specification Summary & Compliance

This extra wide hex nut features precise 1 3/4"-5 UNC coarse threads with Class 2B thread fit per ASME B18.2.2 standards, ensuring dimensional accuracy and interchangeability. The nut measures 2 3/4" across flats with a 1 23/32" height, providing substantial bearing surface. Manufacturing complies with RoHS 3 (2015/863/EU) requirements under exemption 6(c) for lead in copper alloys, maintaining mechanical properties while meeting environmental regulations. The right-hand thread direction and external hex drive conform to industry standards for compatibility with common installation tools and mating components.
