• Enhanced load distribution with 1/2" flange diameter that reduces surface pressure and prevents damage to connected materials
• Precise thread engagement with Class 2B thread fit ensuring reliable, consistent performance in critical assemblies
• Industry-standard compatibility with UNF fine thread (10-32) specifications for seamless integration into existing systems
• Easy installation and removal using standard external hex drive tools, reducing assembly time and maintenance costs
• Full regulatory compliance meeting REACH and RoHS 3 environmental standards for global industrial applications

Professional Applications & Engineering Value

This 10-32 UNF serrated flange locknut delivers critical vibration resistance in demanding industrial environments where mechanical shocks and constant motion threaten fastener integrity. The 316 stainless steel construction provides superior corrosion resistance against chemicals, saltwater, and extreme temperatures, making it ideal for marine equipment, chemical processing plants, and food machinery. The serrated locking mechanism creates permanent resistance to rotation by embedding into mating surfaces, eliminating the need for additional locking components. Combined with the 1/2" flange diameter, this design distributes clamping force over a wider area, preventing surface damage while maintaining secure connections in heavy-duty applications such as automotive assemblies, industrial machinery, and structural frameworks where reliability is paramount.

Specification Summary & Compliance

This flange locknut features Class 2B thread fit tolerance for precise engagement with mating components, manufactured to UNF fine thread standards (10-32) with right-hand thread direction. The external hex drive (3/8" width) and standard hex profile ensure compatibility with common tools. Product meets REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) compliance requirements, confirming environmental safety and regulatory acceptance for industrial use worldwide.
