Professional Applications & Engineering Value

This 1"-14 UNC flange nut in 316 stainless steel addresses critical engineering challenges in corrosive and high-load environments. The coarse thread design and Class 2B thread fit facilitate quick installation while maintaining grip under dynamic stresses, minimizing loosening in vibrating machinery. Its 2" flange diameter effectively spreads clamping force, protecting soft or composite surfaces from indentation and fatigue. Ideal for industrial applications like structural frameworks, piping systems, and heavy equipment, this external hex flange nut combines chemical resistance with mechanical strength, ensuring reliability in sectors such as chemical processing, marine engineering, and outdoor infrastructure where exposure to moisture and aggressive agents is common.

Specification Summary & Compliance

This flange nut adheres to UNC coarse thread standards with a Class 2B thread fit for consistent dimensional accuracy. It meets manufacturing specifications for a standard hex nut profile, with precise measurements including a 2" flange diameter, 0.25" flange thickness, and right-hand thread direction. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for use in regulated industrial and international markets.
