Metric washer and lockwasher "J" standard?

Metric washer and lockwasher "J" standard?

Is there a "J" fastener part standard for Metric washers and lockwashers? There is a J2655 for Inch dimensioned washers but I am having no luck finding a similar standard for the metric.

Thanks for your help.

RE: Metric washer and lockwasher "J" standard?

No, SAE canceled their automotive washer standard.  SAE J2655 is from the Ship systems group.  ASME B18.22.1 covers washers, but I think it is inch series as well.  One of the ISO standards is probably your best option, e.g. ISO 10669, 10673, 7089, etc.  Use the following link for more information:

The ISO standards are good ones.  If you must have a US-based standard, try ASME B18.22M Metric Plain Washers.
