Professional Applications & Engineering Value

This Grade 8 flange locknut delivers critical vibration resistance where conventional fasteners fail. The black-phosphate steel construction provides exceptional tensile strength while the precision serrations create permanent locking action by embedding into contact surfaces. Engineered for heavy-duty industrial applications including machinery, automotive assemblies, and construction equipment, this 3/8"-16 UNC coarse thread nut maintains clamp force under extreme vibration and thermal cycling. The integrated 3/4" flange distributes load evenly, preventing surface damage while the external hex drive ensures compatibility with standard tools. This comprehensive locking solution addresses the fundamental challenge of maintaining joint integrity in high-vibration environments.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2B thread fit for consistent engagement and reliable performance. The UNC coarse thread profile ensures compatibility with standard industrial components while the 9/16" width and 11/32" height provide optimal dimensional stability. This flange locknut fully complies with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring environmental responsibility and workplace safety. The Grade 8 strength classification guarantees mechanical properties suitable for the most demanding fastening applications.
