K Lock Hex Nut, Stainless Steel 18.8 (Inch)
Stainless Steel 18-8 K Lock Hex Nuts are all-metal, self-locking fasteners designed to resist loosening under vibration and dynamic loads. Manufactured from corrosion-resistant 18-8 stainless steel (approximately 18% chromium and 8% nickel), these nuts feature serrated external teeth on the top flange that grip the mating surface to provide a strong mechanical lock. The all-metal design eliminates the need for nylon inserts, making these locknuts ideal for high-temperature and heavy-duty applications.
Engineered for long-lasting durability, Stainless 18-8 K Lock Hex Nuts combine the corrosion resistance of stainless steel with reliable locking performance. The serrated flange provides excellent vibration resistance while maintaining consistent clamping force, even in environments exposed to moisture, chemicals, or salt air. Commonly used in machinery, automotive, and marine applications, these nuts ensure secure fastening without damaging the mating surface and maintain their locking ability through multiple installations.
