the term is "lockwired" I've never heard of 'wire nutted'.

what is more often used is a castellated nut with a split pin through
a hole in the bolt. this is used on hinge bolts.

what I think you are referring to is a hexagon nut is drilled through
the peak of the hex from flat to flat. I have no idea how they
actually do it without breaking drills.
it appears to me to be the most difficult drilling I could imagine
although thinking about it all the nuts done this way are brass so
maybe it is easy with a jig.

what is often done is not to bother changing the nut but to create a
washer with a lobe. the lobe has a hole through it and is bent up
clear of the underlying surface. the lobe is lockwired to something.
on the washer you bend a section or two up onto the flat of the bolt.
something like this is used on marvel schebler carburettor bodies.

there is also the method used on a glider I know. the counter weight
is screwed on to a support. both pieces have opposite side flats.
a washer is used between them. one side is bent up, the other side
bent down.

if none of these work for you describe the application more fully and
I'll try again.
