What vehicle are you working on?
1/4 x 20 bolt, so I'm assuming this bolt is for the oil pan perimeter?

Are your oil pan threads stripped too?
I’ve had drain bolts(HONDA) that stripped but the pan threads were still good and all I did was install a new bolt.

Yeah, what car or light truck uses 1/4-20 for a drain (title says drain)?
And yes, 1/2‐20 is a ginormous step up.
If it's really 1/4-20, I'd run a 5/16-18 tap in there as-is. You could also go M8x1.25 if you're intercontinental and you eat French toast.
But you need to provide more info first.

1/4 is tiny.
You must mean the oil pan bolt, not the drain bolt? The drain bolt is 1/2 x 20. If its a bolt holding the pan on, i'd helicoil it.
1/2" - 20 and just get a piggy back for it.
So it is an oil PAN bolt? One of many that secure the oil pan to the engine block. Nothing to do with the oil drain…
Correct?
No way a 1/2” self tapping plug is going into a 1/2” hole.

I would just install a 1/4-20 helicoil, no need to remove the pan.
The drain bolt is not 1/4 x 20 as you stated in the first post.
Maybe tow this to a shop to fix
Have you been able to get the rest of the Bolt out? If not use a tool to back it out then time cert or re-tap.
Show us some pics of this. The pan and the bolt.
Is this a piggyback plug? A small bolt in a larger one.
I'm thinking it has to be, as the stock size is 1/2 x 20. Hopefully he will provide pics.
