Screws for underside of throttle body

I believe 2 or 3 of the screws broke off in the holes around the coolant throttle body water jackets. Can anyone tell me what size they are?

Re: Screws for underside of throttle body

did you get any out that are intact? they are metric and can be matched up at a hardware store. i had the same problem and was able to get the broken ones out after soaking in w-40 and using vice grips.

Re: Screws for underside of throttle body

Okay, if I have to I'll pull one out of the throttle body. I was hoping I could get away without doing that so I didn't have to disassemble, reassemble, go get the bolt, then disassemble again.

If anyone happens to know the exact size I'd greatly appreciate it.
