Help needed with this joint.

[chas522]

Need help. This joint will not stay tight. Firmly screwed together, after just 3 or 4 hits, it needs tightened again. Keeps coming loose. What can be done? Hits good when tight but just annoying to continually re-tighten. Thanks for any suggestions. Charlie

Is the shaft original to the cue? I see the shaft does not have threads for a while. How far down in the shaft before the threads start? Looks like a short pin, maybe only a few threads at the end of the pin are actually holding it on.

could make a couple rounds with teflon tape ... it might help if the threads are loose
worth a shot and cheap

What I see in the image is that both faces (butt and shaft) are beveled, thus all the force is being restrained by a narrow band near the outside edge of the thread (inside of the butt and shaft).

What you need to do is find a cue repair person and have both faces "faced" which is a lathe term denoting making the face perpendicular to the axial center of the batt or shaft. The repair time is mostly setup--making sure the [butt or shaft] is perfectly centered and true to the lathe axis.

Threads to not stay tight because there is friction in the threads, but because a greater force is applied on the faces holding tension on the threads. {In the same way a nut spins on a typical thread, but when tightened (torqued) holds <essentially> forever.}
