Professional Applications & Engineering Value

This Grade 5 Titanium locknut with nylon insert locking technology addresses critical vibration-induced loosening challenges in demanding industrial applications. The UNC coarse thread design combined with Class 2B fit provides optimal thread engagement while resisting cross-threading during installation. Engineered for aerospace, automotive, and heavy machinery applications where vibration resistance and weight reduction are paramount, the titanium construction maintains integrity in high-temperature environments where steel fasteners might compromise. The external hex drive style ensures reliable torque application while the nylon insert creates consistent locking force without damaging mating threads, making it ideal for maintenance-critical assemblies requiring repeated disassembly and reassembly.

Specification Summary & Compliance

This 1/4"-20 UNC coarse thread locknut features Class 2B thread fit tolerances per ANSI/ASME B1.1 standards, ensuring precise thread engagement and consistent performance. The standard hex profile measures 7/16" across flats with 5/16" height for universal tool compatibility. Manufactured from Grade 5 Titanium with right-hand thread direction and nylon insert locking mechanism. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting the latest environmental and safety standards for industrial fasteners.
