Product application

       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. A zinc plating prevents rust in wet areas. Combine with Class 10.9 metric bolts, which have similar strength. All are reusable but lose holding power after each use.

These locknuts meet ISO 7040 and ISO 7041-2 (formerly DIN 985 and 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.
