Professional Applications & Engineering Value
Engineered for demanding industrial applications, this heavy-duty hex nut combines 316 stainless steel's corrosion resistance with ASTM Grade 8M high-strength properties to solve critical challenges in construction, marine, and chemical processing equipment. The extra wide hex profile provides a larger wrenching surface, minimizing tool slippage during high-torque installations and enabling secure fastening in hard-to-reach areas. With its coarse UN threading (1 1/4"-8) and Class 2B thread fit, it ensures rapid assembly and reliable performance in vibrating machinery, structural frameworks, and heavy-load bearing assemblies where durability and thread integrity are paramount.
Specification Summary & Compliance
This hex nut features 1 1/4"-8 coarse UN threads with Class 2B thread fit for precise dimensional accuracy, manufactured in compliance with ASTM A194 specifications. The ASTM Grade 8M certification ensures consistent mechanical properties, while the 316 stainless steel material provides optimal corrosion resistance. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards is verified, meeting current environmental and safety regulations for industrial components.
