I presume you mean the head of the bolt is stripped. Try some vice grips or a pipe wrench, or use a grinder to put a flat spot on each side of it. There are also some special sockets you can buy that are made to grip anything. I am told they work rather well.
How do u fix a stripped out oil pan
You will have to remove the pan completely by undoing all the bolts and then once the oil pan (sump cover) is removed, it is a simple matter to remove the plug, retap/rethread the hole and replace the plug with a new one.
No, mine's fine, thanks.

You can suck the oil out of the engine by going down through the dipstick tube and changing the filter or you will have to get the drain plug out and have the oil pan repaired. You can purchase a drain plug that will work where one is stripped out. Go to any auto parts store and explain the situation.
If you have a stripped oil plug, first try using a larger plug or a thread repair kit designed for stripped threads. Alternatively, you can apply a thread sealant or tape to help create a better seal. If these methods don't work, consider replacing the oil pan or consulting a mechanic for professional repair. Always ensure the oil plug is securely fastened to prevent leaks.
Over tightening the drain plug.
It is always better to restore the stripped drain pan back to its original size with a steel insert.
its either stripped or someone did it.
The plug unscrews by turning it counter-clockwise. Take the stripped plug to a good auto parts store. There are oversized, self-tapping plugs available, but they will need to match yours up to the correct replacement.
Is it just the oil plug that's stripped or is it the oil pan? If it's only the plug, get a new one from the dealer or a local part store (they are quite cheap). If it's your oil pan, then that's a pain. You'll probably have to put in a self tapping oversized plug or replace the oil pan. I would stay away from those cheap rubber oil plug replacement kits that fit in with a plastic screwdriver.
This seems to be a problem with aluminum oil pans. I just did it today and found an answer with an oversized self-tapping oil plug. Found one at my auto parts store for $2.99.
