Professional Applications & Engineering Value
This Grade 5 zinc-plated steel locknut with nylon insert delivers exceptional engineering value in applications where vibration-induced loosening compromises safety and performance. The coarse UNC threads (1"-8) provide excellent engagement in softer materials and faster assembly times, while the Class 2B thread fit ensures consistent clamping force without galling or cross-threading. The nylon insert creates constant radial pressure that resists back-off under cyclic loading, making it ideal for heavy machinery, automotive assemblies, and industrial equipment subjected to continuous vibration. The zinc plating offers sacrificial corrosion protection, extending service life in environments with moisture or chemical exposure, while maintaining the Grade 5 strength rating for high-stress applications.
Specification Summary & Compliance
This locknut features 1"-8 UNC coarse threads with Class 2B thread fit tolerance for reliable engagement. Manufactured to Grade 5 strength specifications with standard external hex drive (1-7/16" width) for proper torque application. The nylon insert locking mechanism is rated for temperatures up to 220°F maximum. Fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, ensuring safe use in industrial applications worldwide.
