Metric DIN982 Nylon Insert Flange Lock Nut Zinc Plated Grade 8 Hex Nylon Lock Nut

Product Description:

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.

Black ultra-corrosion-resistant coated steel locknuts are more corrosion resistant in wet environments than zinc- and zinc yellow-chromate plated steel locknuts. They're also known as black luster locknuts.
