Who is being rude, arrogant, bullyish or whatever term you prefer to ennoble YOU with?
I'm not just having fun, I do know what I'm talking about. No resistors involved, not a matter of my opinion versus yours.
The OP asked what tap to use for the screws shown in the photo.
There is no tap you necessary. Drill a hole the same diameter as the minor diameter of the fastener shown. Insert fastener between two sheets of metal and turn clockwise to fasten.
That was fun.
