Did this once to a worn female thread in the block of a VW air cooled engine where the oxygen sensor (if I remember correctly) screwed in: Clean out the inside of the worn threads with a degreasing fluid, and then keep cleaning it many times over with alcohol till it is very, very clean and dry. Get an expendable old shutter release cord with good threads on it. Fill the worn threads with J B WELD. Put a generous coating of Cutting and Tapping fluid on to the threaded end of a shutter release cord. As soon as the J B WELD begins to set, carefully screw in the threaded end. After the J B WELD dries thoroughly (I waited 24 hours back when). Now screw out the threaded end of the shutter release cord. It worked on my VW engine years ago, and I was able to screw in a new oxygen sensor. Will it work on a worn small shutter release socket? Can't say, but I'd give it a try. May work as a temporary fix.
