I don't see why it should be a problem for them. Generally speaking it helps to give you a bigger target for your hammer (and punch) to leave the nut on - not done up tight of course, just on enough. That way you also tend to mash the nut not the threads - and it can be hacksawed off if you do loosen the cotter pin and can't undo the nut.
