Re: Fault analysis undertaken and fix identified
If you're using blue loctite on screws that small, you're doing it wrong. Purple is the stuff you're looking for.
The factory-applied blue stuff is actually a plastic that's melted with some ugly solvents so that it can be machine-applied to fasteners and allowed to dry. That way you don't end up with assembly workers putting the wrong amount on, and they don't get glued to the conveyor.
