Tried to Clean MAF, found stripped screws

Like the title says, I tried to clean the MAF sensor and found that both of the screws that hold the sensor in place were stripped by one of the previous owners. I tried all sorts of different philip and flathead screwdriver sizes as well as duct taping to try and make them fit to no avail.

Has anyone run into this problem? I know this seems like a more general question for tackling stripped screws as a whole.

I have run into aimar issues. For this I am thinking one of those reverse out bits that you can buy from Lowes or Home Depot will do the trick.
 
Happens a lot. One of mine is not stripped, but cross threaded. On another stripped bolt I just too my dremel knock-off and cut a long gash along the top of the head and then used a large flathead to get it out.

2,000 posts wooo! Oh wait... I spend too much time on here...
 
I cut a slot in the head of each screw with a dremel, then turned them out with a regular screwdriver, worked great and didn't even have to replace them. I just use regular instead of Phillips now.

Happened to me. I ended up just drilling the screws out. I zip tied the maf back in. Thet was supposed to be a temp fix until I got new screws, but it's been 3 months and it hasn't thrown any codes so I haven't touched it
 
I don't think I want to use a dremel because the screws aren't exposed past the MAF housing, they're actually further below it. So I'd have to start cutting through the MAF and I would rather avoid that haha

I'll try using a drill bit and then walk down the street to find a screw extracting kit. Thanks for the help guys.

Well, if you drill out the head, you can probably just turn out the leftover stem with a pair of Vice-Grips. Screw extractor probably won't work on something that small.
 
Just happened to me earlier this week. Screw extractor did the trick. I replaced them with new screws then. M4 x10mm is the size you need for replacement screws.

You need to use JIS spec screwdrivers. SAE Phillips will strip Japanese screws every time.

You might even still be able to turn the stripped screw if you use the correct tool as it will reach undamaged metal. No guarantee though.

I replaced the factory screws with Allen heads. Much easier to remove in that spot.

Allen head screws are my best friends. I've replace several with them, almost impossible to strip them.

Even home depot will carry some.

Ahh that's right, I have the older turbine style so the screws are off to the side. Forgot about that.
 
Found this in an old post of mine. Also a big thumbs down to Toyota for this cheap design. They could have chose just about any type of bolt that would not strip but instead chose to save probably a nickel by using the cheapest they could find. I removed the entire airbox to get better access. From my post a few years ago - the replacement part number

I used a dremel to cut a groove and got them out. I then found the best replacement at Home Depot

Part number 30699-82558 4mmx10mm cap screw with socket head
I can now use a hex wrench and never strip them again.
 
+1 on the vice grips. The brass screws that Toyota put everywhere on these things are really my only beef with the entire vehicle.
MAF, IAC, grab handles, auto gear shift, etc. If a dremel won't fit, a pair of needle-nosed vice grips will do it.
For future reference (i know you didn't strip these) spray with WD40, then use a stubby or right angle Phillips head to screw the screw TIGHTER to break the seal, then back it out. Put as much pressure as possible to maintain a tight 'grip'.
