Yes it should be the same standard for any derailleur made today.
You could try threading the derailleur bolt (or another derailleur bolt removed from a broken derailleur you have laying around) in from the back - this can sometimes be done to partially clean up the pedal threads on partially cross-threaded crankarms. You could also get the right tap and clean out the threads that way. Or you could buy a new derailleur hanger (assuming it is a replaceable derailleur hanger).
