Professional Applications & Engineering Value

This 10-24 UNC coarse thread locknut delivers exceptional engineering value in applications where vibration-induced loosening poses significant operational risks. The black zinc-plated steel construction combined with the external-tooth lock washer creates a permanent locking mechanism that withstands extreme dynamic loads in machinery, automotive assemblies, and industrial equipment. The external hex drive style ensures reliable torque application during installation, while the Class 2B thread fit guarantees consistent engagement with mating components. This heavy-duty solution effectively eliminates the need for secondary locking devices, reducing assembly time and maintenance costs in demanding industrial environments where vibration resistance and long-term reliability are critical performance requirements.

Specification Summary & Compliance

This locknut features 10-24 UNC coarse threads with Class 2B thread fit tolerance, ensuring precise compatibility with standard fastening systems. The component measures 3/8" width and 5/32" height, manufactured from steel with black zinc-plated surface treatment for corrosion resistance. The integrated external-tooth lock washer (0.406" OD, steel material) provides the primary locking mechanism. The product fully complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, making it suitable for industrial applications requiring adherence to international compliance standards.
