Hmm. Well, on the few I've done, those long-ish jacks of about 1/2" or slightly less diameter have a hex nut on the inside, against the tailblock, and a corresponding pair on the outside, and that "nail hole" absolutely allowed me to tighten the outside hex nut against the outside of the guitar while preventing the threaded outer part of that endpin jack from rotating. When that's done, on the typical setup, the "strap button" part threads down over the smaller diameter part left exposed, and that covers the hex nut that fixes the jack in place. I only hand tighten that outer, button part, but will put a drop of blue Loc-tite on it. Haven't needed any other tools for that, but maybe I'm misunderstanding the jack type, as I've not done a mandolin!
p.s. (edit) the length of the jack that extends out and should be about flush with the strap-button cap piece is a bit critical, at least you don't want it too short, or the 1/4" plug may not go in far enough to get "locked" in by the tip contact bit, allowing the cable/cord to disconnect or even fall out with just a little tug.
