• Enhanced load distribution with 1/2" flange diameter that reduces surface pressure and prevents damage to connected materials
• Corrosion-resistant protection with zinc plating that provides durable surface finish for extended service life in industrial environments
• Precise thread engagement with Class 2B thread fit ensuring reliable, consistent performance in 10-32 UNF fine thread applications
• Easy installation and removal using standard 3/8" external hex drive compatible with common wrenching tools
• Regulatory compliance assurance meeting both REACH and RoHS 3 standards for safe, environmentally responsible manufacturing
• Optimized for fine thread applications with UNF thread spacing providing superior holding power in precision assemblies

Professional Applications & Engineering Value

This zinc-plated steel flange lock nut delivers critical vibration resistance in demanding industrial applications where secure fastening is paramount. The serrated locking mechanism creates permanent resistance to rotational loosening, making it ideal for automotive assemblies, machinery frames, and electrical enclosures subject to constant motion or vibration. The integrated 1/2" flange eliminates the need for separate washers while distributing clamp load over a wider area, preventing surface damage to softer materials. Engineered with 10-32 UNF fine threads and Class 2B thread fit, this nut maintains precise engagement in applications requiring fine adjustment capabilities. The external hex drive design ensures compatibility with standard tools, streamlining installation in high-volume production environments while the zinc plating provides essential corrosion protection for extended service life.

Specification Summary & Compliance

This flange lock nut features Class 2B thread fit tolerance for consistent engagement in 10-32 UNF fine thread applications with right-hand threading. Manufacturing complies with UNF thread standards and incorporates a standard hex profile with 3/8" width and 7/32" height. The product is fully compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring environmental responsibility and material safety in industrial applications.
