Professional Applications & Engineering Value

This 7/16"-14 UNC locknut delivers critical vibration resistance where conventional fasteners fail. The distorted thread technology creates intentional interference at the top threads, generating constant friction that prevents loosening under dynamic loads. Manufactured from zinc-plated steel, it provides essential corrosion protection for machinery, automotive, and construction equipment exposed to harsh environments. The external hex drive allows for standard wrench access in confined spaces, while the Class 2B thread fit ensures smooth installation without compromising locking performance. Engineered to ASTM Grade C standards, this heavy-duty top lock nut maintains clamp force in high-vibration applications from power transmission systems to industrial machinery, solving the persistent challenge of fastener loosening in dynamic environments.

Specification Summary & Compliance

This locknut features 7/16"-14 UNC coarse threads with Class 2B thread fit for precision engagement. The distorted thread locking mechanism operates on the top section of the nut, maintaining full thread contact while providing secure locking action. Dimensions include 11/16" width across flats and 3/8" height. Manufactured to ASTM Grade C specifications for mechanical properties and performance. Fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards for industrial use.
