[QUOTE=sknhgy;12060969] So, I stripped the 10mm nut trying to get it off. TE]

If it makes you feel any better, I've stripped nuts too, trying to get them off.
Be glad it wasn't something expensive like stripping a crank when using an puller (extractor ?).

After I've settled down, I shrug it off as a lesson...
Sometimes the cost per lesson is on the steep part of the learning curve.
