Professional Applications & Engineering Value

This serrated flange lock nut delivers critical vibration resistance in demanding industrial applications where 18-8 stainless steel provides essential corrosion protection. The UNC coarse thread design ensures rapid assembly while maintaining secure fastening in machinery, automotive, and construction equipment. The integrated 3/4" flange eliminates the need for separate washers, reducing component count and installation time. External hex drive compatibility allows for standard tooling, while the serrated locking mechanism bites into mating surfaces to prevent rotational loosening from shock and vibration - solving common failure points in dynamic assemblies.

Specification Summary & Compliance

Manufactured to precise Class 2B thread fit standards with 3/8"-16 UNC coarse threads and right-hand thread direction. Features a 9/16" width across flats and 11/32" height profile. The 0.12" flange thickness provides structural integrity while the 3/4" flange diameter offers optimal load distribution. Fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations for industrial applications worldwide.
