It can do some electrical shocks, but usually when the anodized layer on screws is damaged. Try some of those:
- Add little bit (really, little bit, as it’s M2 thread) of PTFE paste on the screw thread
- Separate thread and screw from each other by using “kapton tape”
- Isolate the screw head with insulation tape. A nice round sticker on top.
- Or use any other polymer / plastic insulation.
