MB Series Bearing Lockwashers – ISO Metric

The MB series is the ISO metric bearing lockwasher and the mating half of the KM, KML and KMM locknuts. Unlike inch-design lockwashers it has no bent key, and its key is shorter — a consequence of ISO 2982, the first international lockwasher standard, approved in 1971 after eight years of cooperative work between national standards bodies.
