Professional Applications & Engineering Value

This 10-32 UNF locknut with integrated external-tooth lock washer addresses critical vibration-induced loosening challenges in industrial machinery, automotive systems, and heavy equipment. The black zinc-plated steel construction provides essential corrosion resistance while maintaining structural integrity under repetitive stress cycles. The fine thread spacing of the UNF thread profile offers superior clamping force distribution, making it ideal for precision assemblies where vibration resistance is paramount. The external hex drive design ensures compatibility with standard tools, reducing installation time and improving maintenance efficiency. Engineered for heavy-duty applications, this locking fastener system delivers reliable performance in environments where constant motion and mechanical stress would compromise conventional fasteners.

Specification Summary & Compliance

This locknut features Class 2B thread fit per UNF standards with right-hand thread direction and fine thread spacing. Dimensions include 3/8" width across flats and 5/32" height. The assembly incorporates an external-tooth lock washer with 0.406" outer diameter manufactured from steel. The product is fully compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) directives, ensuring environmental responsibility and workplace safety standards are met for industrial applications.
