If not irreparably damaged, you can often 'chase' threads by running a correct tap through the hole.

If irreparably damaged, is there enough room for something like a Helicoil or Permacoil?

We can not see, what you see. You therefore, are the best judge. Could you not post a picture?

Could you not post a picture?But he's already 'not posted' a picture...
Maybe if he did post a picture that would help.

Can it be tapped-out to the next gland size up (obviously not if it is an EEx d installation in a hazardous area)?

Silly question, but are any codes involved? Like NEC or BS?

I am supposing that if any applicable codes were in play our original anonymous poster would certainly have advised us.

Well, maybe not.

Codes? CODES?? We don't need no stinking codes! (Paraphrase from Treasure of the Sierra Madre.)

What material is the damaged thread made of (some are plastic while others are metal)?

Is it being installed in a hazardous area (in which case entry modification options are seriously limited)?

If this is for an industrial application only then drilling the hole out to the next size up and using a reducer gland may also be an option.
