On the plastic with thread cutting screws, use very light
touch and carefully screw in. It will bind if not aligned well.
Of course, if the hole has already been abused many times,
this doesn't work as well.
I've usually thrown in the towel and just grabbed some apropriately-
sized ABS stock and the methylene chloride. Apply solvent, tap it
into the old hole and let set. Drill for new holes.
Good as new.
You can get ABS rod stock in very small diameters (3 mm) as "ABS
welding rod".
