Saw exactly this happen on flight deck of USS Midway during 1979. While troubleshooting APD10 radar, the hydraulics guy that was helping me shorted the 400Hz bus to the box containing the power supply, and a star washer vaporized because part of the converter was floated. The star washer was not authorized construction.

I was talking about serrated-headed screws, not star washers.
