If you are trying to repair interior threads a tap IS what you need.
However, if the threads are completely torched you'll have to go to a
little thing they call the Heli-coil.

You can drill out the old threads and use the corresponding Heli-coil
tap to set up your new hole to accept a tiny coil of new threads that
you srew into place witha cool little tool.

Auto shops use these to REPLACE the threads on cylinderheads and main
bearing bolt holes. You don't have to go to a bigger bolt or pedal size
because your threads and the hole are restored to there original size. A
little loc-tite sets everything just fine.
