S-92501A430 3/8"-24 Locknuts

Key Features & Benefits at a Glance

• Superior vibration resistance through top lock distorted thread design, preventing loosening in high-stress environments
• Enhanced corrosion protection with cadmium-plated steel construction, extending service life in harsh industrial conditions
• Reliable load-bearing capacity meeting ASTM Grade C standards, ensuring consistent performance under heavy loads
• Precise thread engagement with Class 2B thread fit and fine UNF threading, delivering accurate fastening without cross-threading
• Easy installation and removal using standard external hex drive, compatible with common wrench tools
• Optimized size profile (9/16" width × 21/64" height) for space-constrained applications while maintaining full locking functionality
• Right-hand thread direction for standard assembly procedures, reducing installation errors

Professional Applications & Engineering Value

This 3/8"-24 UNF locknut with top lock distorted thread technology addresses critical vibration-induced failure points in industrial machinery and automotive systems. The cadmium-plated steel construction provides essential corrosion resistance for equipment operating in demanding environments, while the fine thread spacing ensures superior clamping force distribution. Engineers specify this external hex locknut for applications requiring maintained tension under dynamic loads, particularly in assembly lines, heavy equipment, and transportation systems where vibration resistance is paramount. The distorted thread profile creates consistent interference fit, eliminating the need for secondary locking devices and reducing maintenance intervals.
