Professional Applications & Engineering Value

This heavy-duty hex nut delivers critical performance advantages in demanding industrial settings where corrosion resistance and structural integrity are paramount. The 316 stainless steel composition provides exceptional protection against chemical exposure and atmospheric corrosion, making it ideal for marine, chemical processing, and offshore applications. The extra wide hex profile significantly increases bearing surface area, distributing clamping forces more effectively to prevent joint loosening under vibration and dynamic loads. With its coarse thread spacing and Class 2B thread fit, this nut ensures rapid installation while maintaining precise engagement with mating components. Engineered to ASTM A194 specifications, it offers reliable performance in structural connections, heavy machinery, and infrastructure projects where failure is not an option.

Specification Summary & Compliance

This 1 1/2"-8 extra wide hex nut features UN coarse threads with Class 2B thread fit tolerance for consistent mating performance. Manufactured from ASTM Grade 8M 316 stainless steel to ASTM A194 specifications, it delivers reliable mechanical properties for demanding applications. The nut measures 2 3/8" across flats and 1 1/2" in height, providing substantial bearing surface. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) ensures environmental responsibility and regulatory adherence for global industrial use.
