Professional Applications & Engineering Value
This 5/16"-18 UNC Flex-Top Locknut delivers critical vibration resistance where conventional fasteners fail. The 18-8 stainless steel construction provides excellent corrosion resistance for outdoor equipment, marine applications, and chemical processing facilities. The extra wide hex profile enables higher torque values without stripping, while the flex-top locking mechanism creates consistent friction against mating threads, preventing loosening in high-vibration machinery, automotive assemblies, and industrial equipment. The coarse UNC threading ensures quick installation in production environments, reducing assembly time while maintaining Class 2B thread fit precision for reliable performance across thousands of cycles.
Specification Summary & Compliance
This locknut features 5/16"-18 UNC coarse threading with Class 2B thread fit tolerances for precise engagement. Manufactured to industry standards with external hex drive and right-hand thread direction. Dimensions include 9/16" width across flats and 21/64" height. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial applications.
