Professional Applications & Engineering Value

This Grade 8 steel nylon insert locknut delivers critical vibration resistance in demanding industrial environments where fastener integrity is paramount. The nylon insert locking mechanism creates consistent friction against mating threads, effectively preventing loosening from machinery vibration, thermal cycling, and dynamic loading conditions. Engineered with 1"-14 fine thread spacing and Class 2B thread fit, this external hex locknut ensures precise torque transmission and reliable clamping force in heavy equipment, automotive assemblies, and structural applications. The 220°F maximum temperature rating makes it suitable for environments where thermal stability is required, while the standard hex profile maintains compatibility with existing tooling systems, reducing installation time and costs.

Specification Summary & Compliance

This heavy-duty locknut features Class 2B thread fit per UNS standards with 1"-14 fine thread spacing and right-hand thread direction. Manufactured from high-strength Grade 8 steel with standard hex profile (1 7/16" width) and external hex drive. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, ensuring safe use in regulated industries and applications.
