That's one of the potential uses of the E6000 I have lying around. I can put a dab on the outside of the screw if I were nervous and it's easy to peel off like rubber cement later if I wanted to.
It might be worth getting a Silver Sharpie and making a 6 o'clock Witness mark on the battery cover screw. But so far I have not ever had any issues with those types of screws without doing anything but regular torque.
