Professional Applications & Engineering Value
This 1/4"-28 UNF thin locknut addresses critical vibration-induced loosening challenges in industrial equipment, automotive assemblies, and precision machinery. The Flex-Top locking mechanism creates consistent friction along the thread engagement, eliminating the need for secondary locking components while maintaining Class 2B thread precision. The thin hex nut profile provides significant space advantages in compact designs where standard nuts cannot fit, while the external hex drive ensures compatibility with common wrenching tools. Manufactured from grade steel, this fine thread locknut delivers reliable performance in high-cycle applications where vibration resistance and dimensional stability are paramount.
Specification Summary & Compliance
This locknut features 1/4"-28 UNF fine threads with Class 2B thread fit per ASME/ANSI standards, ensuring precise dimensional tolerance and interchangeability. The external hex measures 7/16" across flats with a 7/32" height for the thin profile configuration. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, making it suitable for global industrial applications requiring environmental compliance.
