My wife has agreed to let me teach her how to shoot pool. I pulled out my 30+ year old cues and will need to get a new shaft for them but I can't seem to identify the threads. I tried going through Seyberts joint by manufacturer page, and the closest I can come is 5/16x14 and 5/16x18 (manufacturers are not listed). Am I correct?

I hoped that my own photo would help but the two pins look pretty similar. I can assure you that my left cue is 5/16-14 and the right is 5/16-18.
I do think yours are 14s but you might want to stop in a pool hall on league night. A Joss/Schon is a 14 and a Meucci is 18. A couple of turns will to tell you.

Now that my photo posted, I am more confident you also have a 14. The only worry is how large a pilot can handle. Most aftermarket shafts have a small pilot but others are larger and might not fit.

Yes they look like 5/16 -14 if you want to be sure just count the number of threads per inch and that will tell you.I hoped that my own photo would help but the two pins look pretty similar. I can assure you that my left cue is 5/16-14 and the right is 5/16-18.

9 threads for 1/2"....so 5/16x18
I don't remember ever trying
, but they are both the same. They both screw into, and sit flat, into each other's shaft.
I have a Biagio and it's an 18.
That's what I counted it to be. They screw into each other, so they are the same.....thanks
Cobra - 5/16-189 threads for 1/2"....so 5/16x18

Just buy a thread pitch, bolt size gauge...easy to use. Also a car guy, I have one similar to this in my rollaway. A local fastener supply store sold the one I bought, marked with their own advertising. I paid $3.95, but that was years ago.:
