Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, this 1"-8 UNC flange nut delivers exceptional performance where vibration resistance and corrosion protection are critical. The 18-8 stainless steel construction provides superior resistance to rust and chemical exposure, making it ideal for marine equipment, chemical processing plants, and outdoor structural assemblies. The integrated 2" flange eliminates the need for separate washers while distributing clamping force over a wider surface area, preventing joint loosening under dynamic loads. With its coarse UNC threading and Class 2B thread fit, this external hex nut ensures quick installation and reliable performance in high-vibration environments such as machinery, transportation equipment, and construction frameworks where maintenance accessibility is essential.

Specification Summary & Compliance

This flange nut features precise Class 2B thread fit with UNC 1"-8 coarse threading and right-hand thread direction. Manufacturing complies with standard inch system measurements featuring 2" flange diameter, 0.25" flange thickness, 1 5/8" width, and 1 1/4" height. The product fully conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across industrial sectors while maintaining consistent dimensional accuracy for reliable assembly performance.
