- Exceptional corrosion resistance from 18-8 stainless steel construction for long-term reliability in harsh environments
- Precise thread engagement with Class 2B fit ensures smooth installation and consistent clamping force
- Easy installation and removal using standard external hex drive tools for efficient maintenance
- Coarse UNC threading provides rapid assembly while maintaining strong holding power
- Environmental compliance with REACH and RoHS 3 standards for global manufacturing applications
Professional Applications & Engineering Value
This 12-24 UNC serrated flange locknut delivers critical vibration resistance where conventional fasteners fail. The 18-8 stainless steel construction provides excellent corrosion resistance for outdoor equipment, marine applications, and chemical processing environments. The serrated locking teeth beneath the flange bite into mating surfaces, creating permanent resistance to rotational forces while the enlarged 19/32" flange diameter distributes clamping load over a wider area, preventing surface damage and maintaining joint integrity. The Class 2B thread fit and coarse UNC threading enable quick installation in automotive assemblies, industrial machinery, and structural frameworks where vibration-induced loosening poses significant safety risks.
Specification Summary & Compliance
This flange locknut features 12-24 UNC coarse threads with Class 2B thread fit for precise engagement. Critical dimensions include 7/16" width across flats, 15/64" height, 19/32" flange diameter, and 0.04" flange thickness. Manufactured from 18-8 stainless steel with external hex drive and right-hand threading. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards for use in regulated industries.
