Professional Applications & Engineering Value
This 8-32 UNC flange nut is engineered to solve critical fastening challenges in demanding industrial settings. The 316 Stainless Steel material offers exceptional resistance to corrosion, pitting, and high temperatures, making it perfect for marine, chemical processing, and food-grade applications where moisture and aggressive substances are present. The external hex drive and coarse thread design facilitate quick installation and disassembly, even in hard-to-reach areas, while the integrated flange eliminates the need for a separate washer, distributing clamp load effectively to prevent joint failure and material fatigue. This nut provides a reliable, long-lasting solution for securing components in machinery, structural assemblies, and heavy-duty equipment, ensuring operational integrity and reducing maintenance downtime.
Specification Summary & Compliance
This flange nut features a Class 2B thread fit for standard tolerance and easy assembly, conforming to UNC coarse thread standards. Key dimensions include a flange diameter of 15/32", height of 13/64", and width of 11/32". It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of restricted hazardous substances and suitable for global industrial use.
