Crowned Top Lock Nut, Stover Lock Nut, Prevailing Torque Lock Nut, Top Lock Locking Nut, and Auto Style Lock Nut all describe the Top Lock Nut. This common metal lock nut is crimped or slightly indented at the top to increase its grip strength. The crimping creates metal-to-metal contact that prevents the nut from loosening in high-vibration applications. Earnest offers the Top Lock Nut in Grade C (equal to Grade 8) to ensure its strength in durability.
