Professional Applications & Engineering Value

This 10-32 UNF flange nut is engineered to solve common assembly challenges in industrial settings. The 18-8 Stainless Steel construction provides excellent resistance to oxidation and chemical exposure, making it ideal for outdoor equipment, food processing machinery, and marine applications where moisture is a concern. The integrated flange acts as a built-in washer, increasing the bearing surface to prevent pull-through on softer materials and maintain joint integrity under vibration. Combined with the Class 2B fine thread fit, this nut delivers a precise, reliable connection that minimizes the risk of thread stripping in high-cycle assembly operations, enhancing overall production efficiency and equipment longevity.

Specification Summary & Compliance

This flange nut conforms to Unified National Fine (UNF) 10-32 thread specifications with a Class 2B thread fit for consistent engagement. It features a standard 3/8" width across flats, a 1/2" flange diameter, and a 0.06" flange thickness. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from restricted hazardous substances.
