Metric Medium-Strength Steel Nylon-Insert Locknuts—Class 8
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.
Most of these locknuts meet ISO 7040 or ISO 10511 (formerly DIN 982 or DIN 985), which are international standards for dimensions. The ISO standards are functionally equivalent to the DIN standards with slight differences in width, height, or tolerances.
Zinc- and zinc yellow-chromate plated steel locknuts are a good option in dry environments. The zinc plating prevents the steel from corroding until the plating wears away.

Metric 18-8 Stainless Steel Nylon-Insert Locknuts
Made from 18-8 stainless steel, these locknuts have good chemical resistance and may be mildly magnetic. The nylon insert grips the bolt to resist loosening without damaging threads. They're reusable, but their holding power lessens with each use. Metric 18-8 stainless steel is also known as A2 stainless steel. These locknuts meet either DIN 982 or DIN 985, which are no longer active standards, but are still a common reference point for designers.
