I had to reverse the jaws on my 6" Bison 3-jaw chuck. I knew the socket cap screws were darn tight as I attempted this once before with a T-handle hex & they wouldn't budge. I ended up finding a workaround at the time so delayed dealing with it. Anyway it today it had to be done & it required a good tug with about 12" extension on the hex key. The threads looked good, no galling or sign of thread retainer glue. I'm the original owner so my conclusion is either they gronk them at the factory or maybe they tighten up over time? I'd like to switch them more frequently & make some soft jaws. So my question is: should I use anti-seize compound or maybe smear of grease or? OTOH I don't want them to loosen either, so wondering what the best treatment is.
