Taking a hypodermic needle with acetone inside, and applying a few micro drops nearest where the threads would be, leave on for a few minutes, repeat, and repeat a couple times more so it would soften the thread-lok... It penetrates into the connection...
If still stubborn, heating the screw head with a medium heat soldering iron (+40w) causes screw to slightly expand and contract, breaking its seating set in the threads... Be patient, and repeat processes with care...
