I think the nut allows you to rotate that vac pipe so that the vac hose for it can fit it easily - just slcken the nut, rotate the vac pipe to the optimum position and connect it to the inlet manifold with a length of vac hose. Then retighten nut, so pipe can't move again.
...AND/OR... it might control spring adjustment... Depending on the nut's postion, the valve will open softly or a more on/off aggressive nature. If it is adjustable, then do road tests to find the optimum positon i.e. so the motor idles smoothly, whilst the valve opens/shuts fully when off/on boost.
