Could not find an exact answer on Google but how big does the T6 Torx screwdriver needs to be? I don’t want to mindlessly buy one online then it turns out that it’s too big (or a bit too small) to fit into the screw hole. I also do not want to strip it. There are 3 six-star screws holding the Wii spindle motor in place that spins the disc. Need to replace it because the spindle is not spinning discs anymore. The lens work however.

Here’s a video showing the size of the tools used: https://www.youtube.com/watch?v=JyCgWsAN
