Professional Applications & Engineering Value
This 10-24 nylon insert locknut delivers critical vibration resistance in demanding industrial environments where loosening under dynamic loads poses significant safety and performance risks. The 18-8 stainless steel construction provides exceptional corrosion resistance, making it ideal for applications exposed to moisture, chemicals, or outdoor conditions. The nylon insert locking mechanism creates consistent friction against the mating bolt, maintaining clamp force without damaging threads. With UNC coarse threads and Class 2B fit, these locknuts ensure reliable engagement in machinery, automotive assemblies, electrical enclosures, and structural frameworks where vibration-induced failure must be prevented. The 220°F temperature rating makes them suitable for engine compartments, industrial equipment, and applications experiencing thermal cycling.
Specification Summary & Compliance
This locknut features 10-24 UNC coarse threads with Class 2B thread fit for precise dimensional accuracy and reliable mating. The external 3/8" hex drive provides standard tool engagement. Manufactured from 18-8 stainless steel with a nylon insert locking element rated for temperatures up to 220°F. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial fastener applications.
