Let me restate the question.

Running and twisting the wire is simple enough.  How do you get that tiny h=
ole through the side of a 12 or 13mm nut?
With as many tiny drill bits as I've broken, it would be easier and che=
aper to just buy them if they are available
someplace.
You can buy a jig to do it

(the 1st hit when I googled 'safety wire drill guide')

=A0or you could make your own with a hunk of metal & a file.

Or, you could just measure the hole depth & make sure that the bolts don't bottom out. As you know, drilling a bolt head is a lot simpler. :-)
