Default Help! Stripped a screw that doesn't exist!

I accidentally stripped one of the screws for the airbag mounting plate and I can't find a part number anywhere! Anyone know what how to find this part or an equivalent? Also anyone got any recommendations on how to go about removing the stripped torx?

Pictured is the plate, upper screw is stripped, and one of the screws are removed so you can see what the screw looks like:

Tap one size larger torx (or a similarly sized hex driver) into the stripped head and try turning that.

If that fails, lightly slot the torx with a rotary cutoff wheel. Take a small chisel and hammer, use it to tap somewhere near the outer edge of the head within the slot you created in order to turn it counter clockwise.

Is this a 991.1 or 991.2? Just saw the PN in the image, this appears to be a 991.2.

Searching around, it looks like that plate is part of the steering wheel assembly itself, which makes the screw integral to the greater part. If a dealership (or someone else here) can't give you a part number for that particular screw, your best bet is to take good measurements of one of the screws and find that exact screw in the parts catalogue (or hardware store).

Running a cut across the top to then be able to use a flat head screw driver may help remove and save the screw for continued use. You can use a dermal with a cutting disk to create the slot.

Don't kill the messenger. I read a in a DIY blog a quick way to get a stripped phillips head screw out. Lay a wide rubber band across the stripped head and push the driver into it. The claim I guess is the rubber will conform into the stripped gaps and give enough friction to twist out the screw. Easy to try but haven't had the occasion to attempt it. May work for torx. If this doesn't work, I agree with grinding a slot into the head or the tool Mac M suggested

I had the same issue when swapping steering wheel.

I used a dremel to cut a flat cut into the head of the screw. I then used a flat heat to unscrew. but first I soaked in PM Blaster and heated with torch. It was stuck.

Yes based on the diagrams I'm finding like the above, doesn't seem like a dealer would have a part number. Trying to figure out of the steering wheel is made by someone else like ZF or something.

I tried hammering in a flat head - it was just the right width and wedged in deep, got some decent torque trying to turn it but the screw is on so tight it stripped again. It's a T20 screw and hole was too small to tap a T25 in, hex was the same story.

Ordered a dremel will try this next though I'm not sure I can get the disk in at the correct angle

Interesting, though not sure if it would work for this. There is a plate behind the screw head, leaving very little to grab

I tried this too, the bit actually makes less contact with the rubber band in there.

The screws are springloaded so I didn't think a spray would help, but I have some Kroil I'll use with the next attempt. What did you replace the screw with?

For replacement screws, try McMaster-Carr or Belmetric.

I just remembered I bought a set of Speed-Outs to extract a stripped screw. Harbor Freight has an extractor set too. Here's a link from Lowes. These worked for me.

I had the same issue. However, I was fortunate to have a number of different torx bit sockets on hand. Wound up getting it loose and reused. Feel sorry for me if I want to put the stock wheel back... Please post a part number if you find one.

love finding new tools! Ordered - thanks

Gluck OP - I often use the dremmel method with a lot of success

Similar concept has worked with electrical tape.

Slot and chisel are your best bet. Use a vice to hold the part.

If you ever worked on old Japanese motor cycles you would be familiar with these.
