I have an extension cord broken and I want to repair it.
It is closed with special head screws, which seems are made only to be tightened.
The head does not allow opening with a normal screwdriver.
I have a set of industrial, special screwdrivers, but none of them helps.
I tried to drill the head of the screw with gold type HSS drill bits, under 0.5 up to 2mm, but it is a very hard material and did not help.
The screws are fixed in plastic/aluminum case of the extension cord. They are not glued. They just need to be unscrewed.
So, how shall loose/open these screws?

Any helpful hint is appreciated.

16 balls are given. All but one are of equal weight. You do not know whether the defective ball is lighter or heavier than the normal balls. You are given a comparison balance. You can use the balance only 3 times. How would you find out which is the defective ball? Is it heavier or lighter?
