I have a heavy-duty massager whose main structure is held together by two
pieces of threaded rod about 3" long. The rods are partially stripped at
the ends; nuts need to be turned to put them on, but they're quite loose. It
doesn't look like it would be possible for me to replace the rods, so I'm
wondering if there's any sane and relatively permanent way to repair the
threads. Whatever I use has to tolerate a LOT of vibration, of course.

If it's a size that's commonly used for pipe hangers, there are couplers
available where you can cut off the damaged section and splice in a nwe
one. However, if they're only 3" long I suspect that replacement would
be your best option. can you post a pic?
replace "roosters" with "cox" to reply.
I've fixed munged threads with a file, if you have a file that can fit in
the thread, you should be able to use the file to make it look like a thread
again. Then, maybe you can try spinning a thread-cutting die on it.
You've stripped the threads off. There is no practical way to fix that
except by replacing the threaded rods.
If you galled the threads so the nut wouldn't thread on, that'd be
different. That could be cleaned out with a thread file.
Or rethreading for smaller size or if it doesn't need to hold much force
peening to create high spots and rethread. Possibly some shim stock
around the thin spot might work. Lots of ways to cobble stuff up; best
would undoubtedly be to replace...
Or, is there a section not used so could shorten existing, use
connecting nut to extend back to original length?
