Professional Applications & Engineering Value

This 3/8"-16 UNC steel locknut with Flex-Top locking technology addresses critical vibration-induced loosening in industrial and automotive systems. The innovative flex-top design creates consistent radial pressure against mating threads, maintaining clamp force under extreme dynamic loads. The thin hex profile (9/32" height) enables installation in space-constrained applications where standard nuts cannot fit, while the external hex drive ensures compatibility with common wrenching tools. Manufactured from high-grade steel with coarse UNC threads, this locknut provides reliable performance in heavy machinery, transportation equipment, and manufacturing systems where vibration resistance and secure fastening are paramount.

Specification Summary & Compliance

This locknut features 3/8"-16 UNC coarse threads with Class 2B thread fit for consistent engagement and proper clearance. Dimensions include 9/16" width across flats and 9/32" height for the thin hex profile. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring restricted substance compliance. Manufacturing follows industry standards for external hex drive locknuts with right-hand thread direction, suitable for various industrial fastening applications requiring vibration-resistant solutions.
