All ball bearings are Metric.
Ball bearings aren't metric when measured with an English micrometer. They may not be standard size but they're certainly not metric either.
What are they if measured with a metric micrometer?
Bendix cover screws
Original bendix cover screws aren't metric, but you can use a metric Allen head screw and make your life easier. They are "close enough" that they work.
"but you can use a metric Allen head screw and make your life easier"
I would imagine if you find a need to measure them with a metric micrometer you could say they're metric ball bearings. Now ain't that handy. It's all up to you. ,''
