So I'm putting my bike back together after getting the fork serviced. I tighten the stem cap, too much apparently, and hear a noise. There is a star-like nut that the stem cap bolt screws into inside the head tube of the fork. It came a little loose so I "gently" hammered it back into place. Is the sole purpose of this nut that is lodged into the head tube to hold the stem cap? I am not sure how vital this is to holding the fork/handlebar/stem together. Anybody know anything about this or have experience with it?

The fork is a Fox 32 120 mm F series.

Thanks.

The stem cap is used to adjust the preload on the headset. The star nut gives you something for the stem cap to pull against. Once you tighten the stem it shouldn't really serve much function.

The star nut and stem cap are used to pre-load the crown race and headset bearings so you can THEN tighten the stem bolts on the steerertube.
That is what actually holds the stem from moving.:thumbsup:
