Side Lock Nuts, or Center Lock Nuts, are common all-metal Hex Lock Nuts with side crimps. These side crimps are engaged when the nut is applied to a male thread. The crimping creates metal-to-metal contact that prevents the nut from loosening in high-vibration applications. Earnest offers Top Lock Nuts in Grades A and 8 to ensure their strength and durability.
