I decided on cleaning my laptop fans today, which I’ve been procrastinating for about a year now because of this one screw. But I just can’t seem to open this with my screwdriver, since whatever I did back when I last opened it it’s nearly circular now. Is there a way to unscrew this?
Jb weld a nut to it.
Also, G Flex is an epoxy formulated for plastics and West Systems has tutorials on their site.
In this case, I’d drill a small hole in the center, put CA or epoxy in it, then screw another screw into the epoxied hole and let it set up.
There’s no need for all that work. Just a dab of epoxy or glue right on top, the any appropriate sized nut on top of that.
Any drilling/dremel work just creates dust and metal shavings.
