Professional Applications & Engineering Value

This 18-8 stainless steel cap locknut delivers critical performance where vibration-induced loosening threatens assembly integrity. The distorted thread locking mechanism creates permanent friction resistance without requiring additional locking components, streamlining installation while maintaining UNC coarse thread compatibility. Engineered for heavy-duty industrial applications including machinery, automotive assemblies, and electrical enclosures, the corrosion-resistant stainless steel construction ensures longevity in demanding environments. The cap nut design provides both secure fastening and a finished appearance, making it ideal for visible applications where both function and aesthetics matter. With Class 2B thread fit precision, this nut maintains consistent clamping force while the external hex drive enables efficient torque application using standard tools.

Specification Summary & Compliance

This cap locknut features 10-24 UNC coarse threading with Class 2B thread fit for precise dimensional accuracy. The standard external hex drive accommodates 3/8" wrench size with an overall height of 13/32". Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial applications worldwide. The right-hand thread direction and distorted thread locking technology provide reliable performance in vibration-prone environments.
