Professional Applications & Engineering Value

This Grade F flange locknut combines multiple engineering advantages to solve critical fastening challenges in industrial equipment, machinery, and automotive assemblies. The nylon insert locking mechanism provides consistent vibration resistance without damaging mating threads, while the integrated 0.81" flange distributes clamping force over a wider area, preventing surface distortion and maintaining joint integrity. Manufactured from zinc-plated steel with 3/8"-24 UNF fine threads, this component delivers reliable performance in high-vibration environments where conventional nuts would loosen. The combination of temperature-resistant nylon (up to 250°F) and Class 2B thread fit ensures precise installation and long-term reliability across diverse operating conditions.

Specification Summary & Compliance

This flange locknut features 3/8"-24 UNF fine threads with Class 2B thread fit for precision engagement. The external hex drive (9/16" width) provides secure tool engagement during installation. Manufacturing complies with Grade F strength requirements and maintains dimensional accuracy per industry standards. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant regarding substance restrictions, ensuring environmental responsibility and regulatory adherence for global industrial applications.
