I concur, the 242 thread locking compound works fine for me.

Also, I ensure I have the compound on the full length of the engaged threads. First, I back the screw out, apply the compound with a toothpick or wire, then start turning the screw so the compound gets dragged into the mating threads. I may apply another drop or two as the screw advances.

And for good measure, I carry a loose 2mm Allen wrench just in case. I can't fit on my Alien multi-tool between the levers and bars.
