On 1920s-ish hardware on a same age door.
Knobs were loose, but set screw was stuck. Someone long ago already stripped the screw thread, so Ive tried to remove it.
Kroil, ATF, etc don't help. I assume there's a combo of human oils, chemical bonding, etc.
Going to break the extractor if I try any harder.
So what's next??
