How do I fix a stripped hole in a vinyl casement window?
I mentioned a longer screw in my comment, I need to expand on this. A longer screw of the same size may need to be inches longer to contact wood framing because of shims. But a longer screw that engages with framing will not affect the gear box functions. A larger screw as some suggest may affect the gear box. I have used longer screws on high precision gear boxes that worked as well or better than the original that stripped out. But going larger may cause offset or problems with the gears in simple from the larger head and or shaft.
