by the way when people say loctite, go for loctite 243 (or blue threadlocker) not superglue which is made under loctite brand by ankle. I prefer 243 to 242 because it is oil resistant.
270 will lock very but is difficult to undo
Avoid 648 which has to by burned to be removed
Also, depending of geography, you may find equivalent permabond product easier to source.
