Avoid all this in first place by doing your own oil changes and tighten the drain bolt nice and snug.
Get a Sharpie and put a nice thick line on the drain bolt at the 12 o'clock position and look at it from time to time.
The 10mm bolt is not a good idea IMHO, it looks like it was made simply to have people have difficulty removing it.
Amazing how Motorrad can source a 10mm drain plug but not decent front disk bolts.
Only use a 6 point socket on the conventional drain bolt. Forget the copper washer, I have reused mine a half a dozen times
and it doesn't leak a drop, the drain bolt never comes loose, and you can forget the idea of torquing the oil filter, too.
