Professional Applications & Engineering Value
This 8-32 UNC serrated flange lock nut is engineered to solve critical challenges in industrial assembly, such as vibration-induced loosening and corrosion. The 316 Stainless Steel material offers exceptional resistance to chemicals and moisture, making it perfect for marine, chemical processing, and outdoor equipment. The serrated locking type bites into the mating surface, creating a permanent lock without damaging components, while the integrated flange acts as a built-in washer to protect surfaces and increase clamp load. Its coarse thread and external hex drive facilitate quick installation in tight spaces, reducing assembly time and maintenance costs in automotive, machinery, and structural applications.
Specification Summary & Compliance
This flange lock nut features a UNC 8-32 coarse thread with a Class 2B thread fit for consistent engagement and reliable performance. The flange diameter is 15/32" with a thickness of 0.02", and it includes a standard hex profile for external drive. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring it is free of hazardous substances and suitable for global industrial use.
