Professional Applications & Engineering Value
This 18-8 stainless steel cap locknut delivers exceptional engineering value in demanding industrial settings where vibration loosening and corrosion present significant challenges. The distorted thread locking technology creates permanent friction along the thread engagement, effectively resisting back-off in high-vibration machinery, automotive assemblies, and outdoor equipment. The UNC coarse threads provide faster installation and better performance in materials prone to stripping, while the stainless steel construction ensures long-term reliability in moist, chemical, or temperature-variable environments. The combination of external hex drive and cap nut profile offers both installation convenience and complete thread protection, making it ideal for applications where fastener integrity and appearance matter equally.
Specification Summary & Compliance
This cap locknut features precise 6-32 UNC coarse threads with Class 2B thread fit for consistent engagement across standard applications. The dimensional specifications include 5/16" width across flats, 11/32" height, and 5/32" thread depth. Manufacturing complies with industry standards for inch system fasteners and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
