PureX Turbo Lock joint pin

[jayman]

I got a PureX shaft with a viking cue I purchased. It has a brass insert with an open thread-less guide area then threads. They are a 5/16"x?? neither 18 or 14 tpi pins thread into it. The threads are in great shape, so assume it's some goofy proprietary thread pitch. Is anyone familiar with these that can let me know what it is? I found a PureX joint called a "Turbo lock joint" but no description of it. I am guessing this shaft is for one of those, but I am just guessing.
Thank you

I found this thread. It was never confirmed, but it looks like it could be a 5/16x10 Mine looks to me to be more of a fine thread than a 10 but I don't know, It may be.

Does it look like this? Think it is also called a Quick-4 by some. I found a source if so.

That's probably it. Thank you. I get tired of every one having a slightly different version of the same thing. Bring on the drill bit!
