Made from medium-strength steel with a nylon insert, these Class 8 metric locknuts are strong enough to use on most machinery and equipment that’s prone to vibration and temperature changes. The nylon insert also won’t damage the threads on your bolt. All are reusable, but their holding power lessens with each use. Pair them with compatible Class 8.8 metric bolts.
