What I have done is cut a good nut into two halfs, position them onto the
good threads and clamp them together. Then back this assembly out over the
boogered threads to straighten them out.

See if you can find a 12TPI thread file. You start filing where the threads a=
re mostly good & keep filing over the damaged threads until you reach the en=
d. If you want to, you can then run a standard 12-24 die onto it afterwards.=
  I got a set of SAE & metric decades ago from J. C. Whitney - May they Rest=
 In Peace.=20

Peace,

I forgot about thread files. It’s a 12-24 stud, so you’d want a 24TPI file, no?

If you want to, you can then run a standard 12-24 die onto it afterwards.  I got a set of SAE & metric decades ago from J. C. Whitney - May they Rest In Peace.

Just had another thought. Depending on how long the stud is, it may be simpler to cut off the damaged end with a dremel and an abrasive wheel. A rule of thumb I’ve used for years (not sure where I got it from - maybe one of my undergrad profs?) is that you want at least one diameter of the fastener above the nut, once it’s fully assembled.
