hexagon-nylon-nuts (with-non-metallic-insert)-style-2

Name: High-Strength Steel Nylon-Insert Locknuts—Grade 8

Material: Carbon Steel

A nylon insert grips the bolt to resist loosening without damaging threads. These nuts are reusable, but their holding power lessens with each use. Made from Grade 8 steel, they're about 25% stronger than medium-strength steel locknuts.

Steel locknuts without a finish are ready to be painted or finished. Black-oxide steel locknuts have a dark surface color and are mildly corrosion-resistant in dry environments.

Zinc yellow-chromate plated steel locknuts resist corrosion in wet environments. A nylon insert keeps metric bolt threads from coming loose due to vibration, wear, and temperature swings. About 25% stronger than medium-strength steel locknuts, these nuts are made of high-strength, Class 10 steel. They're used in valves, pumps, suspension systems, and other high-stress parts. Combine with Class 10.9 metric bolts, which have similar strengths. All are reusable but lose holding power after each use. Zinc-plated steel locknuts are corrosion-resistant in wet environments. Black corrosion-resistant-coated steel nuts are more corrosion-resistant in wet environments than zinc-plated steel nuts. They're also known as black luster nuts. Some of these locknuts meet ISO 10511 (formerly DIN 985) or ISO 7040 (formerly DIN 982), which are international standards for dimensions. The ISO standards are functionally equivalent to the DIN standards with slight differences in width, height, or tolerances.
