I saw a Youtube video where a guy said this is to tighten the tremolo (whammy bar).
Music Man JP6: Fixing Whammy Bar to stay in place (whammy bar adjustments)
But people in the comments were saying that this is actually a, "tremolo height adjustment screw." Wtf is that?.... I know how to tighten the actual set screw so my whammy bar will sit wherever I leave it, or alternatively I can loosen it and the whammy bar will not hold its position. But anyway, point is I like the whammy bar to hold its position and I notice there is a little bit of wobble in the bar when I first reach for it.... Just curious if the wobble is normal and if anyone knows if this spot circled in red does anything important or could fix the wobble?

P.S. My Allan key doesn't seem to do anything on this spot circled in red, even though I can in fact secure the whammy bar in its position where the other set screw is located.

I feel I've done my homework per the references listed below. Just wanted to reach out to this community to see if anyone has experience/advice on maintaining unfinished AAA roasted maple necks from EBMM? My main concerns are whether I should remove the neck from the guitar for this process, and alternatively if I should tape up the body to protect it from the various products?
By extension, any other tips/advice/cautionary tales are appreciated.

So far as I can tell, the steps are:
1)Dilute murphy wood cleaner in warm water/clean back of neck
2)sand/buff (I'll start with a conservative 1000 grit)
3)apply tru-oil/buff
4)apply gun stock wax/buff
