What should I do to fix a plastic (I think it's ABS resin?) hole which has its thread damaged from metal screws?

Drill out and retap at a larger thread size.
On top of that, can insert a coil like thing to get back to the same tread size. I had forgoten what is that thing called. Looks like a spring coil made of Stainless steeel.

Normally this happens when you overtighten so next time when you tighten a metal screw on plastic, please do not use too much force.
Thanks for the replies, everybody.
So far I've heard about filling the hole up with epoxy, re-drilling and re-tapping, but am not sure if I can pull it off.
It's for my 1/10th scale r/c model. The screwholes are quite small, as are the screws used (3x12mm). High-impact crashes places a lot of strain on the plastic chassis so the screw threads also tend to break easily.
Oh can I add a question of something quite similar here? hehehe
I have this external harddisk casing with an internal 80GB harddisk in it.
One of the screw of the external casing has been stripped of it's + sign. Now it's smooth round. Any idea how can i take out the screw? I've brought it to hardware shops but they said to drill another hold into the screw, but it's a dedicate harddisk in it! Any other way to go around doing it? Any advices appreciated.

yes, superglue.
place a drop in the hole then put in the screw. the glue should fill the gap between the metal screw threads and the plastic. once it hardens, it should hold quite well.
use a dremel or rtx cutting disc, at high rpm, cut in a minus groove
abt 20k rpm there abt should be just a single "touch" job without causing unwanted vibrations.
any hobbyists who modify computer casings and do metal work will be able to help you.Oh where can I find anyone doing such a precision job? Wish to know... or else my external harddisk case is forever bonded to this 80GB hard drive..
