Professional Applications & Engineering Value

This zinc-plated steel locknut with integrated external-tooth lock washer addresses critical vibration-induced loosening challenges in demanding industrial and automotive applications. The UNC coarse thread design (6-32) combined with Class 2B thread fit provides reliable engagement while resisting cross-threading during high-speed assembly operations. The external-tooth configuration creates multiple biting points that dig into mating surfaces, maintaining clamp load where standard nuts would fail. The zinc plating offers essential corrosion resistance for equipment exposed to moisture, chemicals, or outdoor elements. Engineered for machinery, conveyor systems, automotive components, and electrical enclosures, this locking solution prevents costly downtime and maintenance by ensuring fasteners remain securely in position despite continuous vibration and dynamic loads.

Specification Summary & Compliance

This locknut features 6-32 UNC coarse threading with Class 2B thread fit for precise dimensional accuracy. The external hex drive measures 5/16" across flats with a total height of 9/64". The integrated external-tooth lock washer has an outer diameter of 0.344" and is manufactured from steel. Manufactured to inch system standards, this component meets industry specifications for locknut applications and complies with relevant industrial fastening standards for material composition and performance requirements.
