screw

I counted 12 threads above the joint collar. If it is a little over 3/4 inch long that would imply a 5/16 X 14TPI. Count how many threads there are in one inch of screw length and measure the outside diameter of the screw.

Chris may be right(5/16 X 18TPI), but it looks a little coarser to me.
Look closely. Hope this helps.

What brand of cue is it? Cuetec has a pin that is 14 TPI that is real close to 5/16 x 14 but is not 5/16. Looks like a 14 TPI to me.

thank you for your input sir
 
It's probably just an illusion or the picture's shadows but those threads don't look like 60 deg-V threads to me.

what does 60 deg V threads mean?sorry bout the question but im a new player so i dont really know that much yet
 
The 60 degree thread form is the typical American standard you see on practically every type of screw available in hardware stores. The come in both coarse and fine threads.

The angles are 30 degrees per side,giving you a 60 degree "included" angle.

Even to the naked eye,they are V shaped.

My best guess is that is a Mezz cue you posted the pic of,with their so-called United Joint.

I've never seen one in person,but it looks like a 5/16-14 to me. The shadows are causing it to appear to not be a V-shaped thread,as best I can tell. Tommy D.
 
Go to the hardware store and purchase a 5/16-18 nut ,try to thread it on (it will just start) if it doesn't thread all the way down then it is most likely a 5/16-14 thread ..
 
eaaier way?

I bet if you just stated the name of the maker of that cue someone could tell you more than you wanted to know about the joint... just a thought. Best of luck! -Josh

Here is a surefire way to figure out what the thread (any thread) is:

Call a machine shop in your area (a good Fastenal or other bolt store will work, also). Ask if someone will look at the screw for you. Take the cue to that person. They will get out a thread gauge (http://www.mcmaster.com/#thread-gauges/=hm4bxp) and a pair of calipers. They will use the calipers to measure the outer diameter of the screw (probably 5/16"). They will then use the thread gauge to measure the pitch of the screw (usually 14tpi or 18tpi, but with all the bastard threads, could be anything).

Give the guy a ten for his time and thank him.

Not a cue maker here...but my PI cues seem to have non-standard pins. They are 18 thread but will not screw together with any other shafts I have and I have over 30 cues with mostly 18 thread pins.

With such a cue the best policy is to put it in the hands of a cue maker or repair man that is willing to deal with it.
