Screws oils/fats ?

Hi people again I have a question. last time it was time again and I put my summer rims on it. the screws were almost not to be loosened anymore. a rim also went on (key slip and fully into the rim). the trollos of mature service have tightened the screws much too dolle. after a long fight I got them down. now I wanted to know if someone oiled the mature screws of you / greases?? I have never seen this before, that this is done but you don’t have to make life difficult for yourself. I didn’t want to get rid of it like that.Could be that a screw could loosen or something. well, I’m curious what you say about it. thank you: Greetings
