Professional Applications & Engineering Value

This brass nylon insert lock nut delivers exceptional engineering value in applications where vibration-induced loosening poses significant reliability concerns. The nylon insert locking mechanism creates consistent friction against mating threads, effectively dampening vibrations in machinery, automotive assemblies, and electrical enclosures. The brass material provides inherent corrosion resistance, making it ideal for marine environments, plumbing systems, and outdoor equipment where moisture exposure is common. With UNC coarse threads and Class 2B thread fit, this locknut ensures quick installation while maintaining precise tolerances for repeated disassembly and reassembly cycles. The 220°F temperature rating of the nylon insert guarantees performance stability in engine compartments, industrial machinery, and other thermally demanding applications where thermal cycling occurs.

Specification Summary & Compliance

This locknut features 1/4"-20 UNC coarse threads with Class 2B thread fit for optimal clearance and engagement. The external hex drive measures 7/16" across flats with a 5/16" height profile for standard tool compatibility. Manufactured to industry standards for right-hand thread direction and nylon insert locking technology. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial applications.
