I've never stripped baffle screws but I've stripped the cup threads into which the baffle screws go many times. I don't see how metal screws would strip before plastic threads. I bet you're about to strip your cup threads, instead.
There is a relatively easy fix described in one of my previous posts a few pages back. Basically, you use a 1/16" (2mm) drill bit to drill out the ruined plastic threads. Blow out the plastic debris. Fill each compartment with super glue and stir it around/tamp it down with a paper clip. Repeat until the super glue has filled each compartment to the top. Use liquid super glue, not the gel which won't flow into such tiny spaces.
Wait 25 hours. Use the same drill bit. Drill on slow speed, straight down with minimal pressure to the depth of the screw theads. Careful to not drill all the way through the cup! The screws will self-tap new threads good for at least 20 modding cycles. I've done some sets 3 times.
