Professional Applications & Engineering Value
These brass locknuts with nylon insert provide critical vibration-resistant fastening solutions for demanding industrial applications. The combination of brass material properties and nylon locking technology addresses common engineering challenges in machinery, automotive, and electrical assemblies where corrosion resistance and maintained clamp load are essential. The UNC coarse thread profile ensures rapid assembly while the Class 2B thread fit guarantees consistent performance across production runs. Particularly valuable in vibration-prone environments, these locknuts prevent spontaneous loosening that can lead to equipment failure, making them ideal for motors, pumps, and precision instruments requiring reliable thread locking performance up to 220°F operating temperatures.
Specification Summary & Compliance
This 4-40 UNC locknut features precise Class 2B thread fit tolerances with standard 1/4" hex drive and 9/64" height dimensions. Manufactured to industry standards for external hex locknuts with right-hand coarse threading. The product is fully compliant with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) standards with applicable exemptions, ensuring environmental responsibility while maintaining performance characteristics.
