- Increased bearing surface from the 1/2" flange diameter, distributing clamp load over wider area
- Quick installation with standard external hex drive design compatible with common tools
- Reliable thread engagement through Class 2B thread fit ensuring consistent performance
- Environmental compliance meeting both RoHS 3 and REACH standards for industrial safety
- Optimized for coarse threading with UNC 10-24 specification providing excellent assembly efficiency
Professional Applications & Engineering Value
This 18-8 stainless steel serrated flange lock nut delivers critical vibration resistance where conventional fasteners fail. The serrated locking mechanism beneath the flange creates permanent friction against mating surfaces, eliminating the need for additional locking components. Engineered with UNC coarse threading and Class 2B thread fit, it maintains precise tolerances while accommodating minor surface imperfections. The corrosion-resistant properties of 18-8 stainless steel make it ideal for automotive assemblies, machinery frames, electrical enclosures, and outdoor equipment exposed to moisture, chemicals, or temperature variations. The integrated hex flange nut design combines washer and nut functions, reducing part count and installation time in high-volume manufacturing environments.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2B thread fit per UNC specifications, ensuring reliable engagement with mating 10-24 UNC coarse threads. The flange measures 1/2" diameter with 0.09" thickness, providing optimal load distribution. This right-hand threaded external hex drive locknut features standard hex nut profile with 3/8" width and 7/32" height. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted substances above threshold limits.
