The ones I have seen have a radial threaded pin. Meaning more of a curve to the valleys of the thread then a 3/8x10. Also, I think they are more like 3/8x8.There is an imported cue line from KAO KAO that has southwest style cues that many companies put their name on that use 3/8x10 pins.
My Dominiak has a 3/8x10 but I don't know if his newer cues have it.
