All Metal Lock Nut
An All Metal Lock Nut is a locking nut designed for high-vibration applications. This common metal lock nut features a crimped or slightly deformed top thread section that increases its grip strength. The crimping creates metal-to-metal contact with the mating threads to resist loosening caused by vibration and repeated movement. This locking design eliminates the need for nylon inserts or additional locking components. An all metal lock nut goes by several names, including crowned top lock nut, Stover lock nut, prevailing torque lock nut, top lock locking nut, and auto style lock nut.
All Metal Lock Nut DIN 980
An All-Metal Lock Nut DIN 980 is a metal self-locking hex nut that conforms to the DIN 980 standard, which specifies dimensions and performance for prevailing torque-type lock nuts. These nuts are designed to resist loosening under vibration and dynamic loads without using nylon inserts or adhesives.
