in that case i would try fohat's suggestion first
For stripped holes, you can start with tiny cylinders of rolled tissue, paper towel, or ordinary paper with no glue.
Next would be the same stuff, but glued in.
Next, the softest wood available, glued or not, then harder woods, with or without glue.
That is my usual repair progression for stripped holes of all types. Often the added compression of just a layer or 2 of paper is enough if you are using machine screws. Otherwise, you will need to create a hole.
If you are using pointed screws (wood or sheet metal type) then they will often tap their own way in.
