I never put anything on rings and never had them come loose. I use a torque screwdriver. I feel this is just dumb luck. I now use PURPLE loctite. The purple is the lowest strength. It is basically only available online, do not even try the hardware or auto store, you are wasting your time. I use this on barrel screws and now scope rings. This can also work on a choke tube that will not stop backing out.
