do i loctite the sprocket?

im replacing a front sprocket on the track bike and i assume i apply loctite to the thread when i do it up.
is that correct?
if thats the go should i use the super strength or is the medium strength ok?
the sprockets were recently replaced on this bike and the goose who did it has threaded the nut so believe it or not the nut actually fell off.
i imagine that could of ended quite badly
