Oink! (Or whatever a Guinea Pig says.)
I put a dab of blue LocTite on Yankee's screws when I installed them a couple of weeks ago. The blue grade shouldn't present a dis-assembly problem, but as noted in other threads, LocTite recommends applying a little heat to the fastener in order to break the material's hold. Just a few seconds with a hot soldering iron against the Allen wrench will do it.
