> The CueTec pin is an oddball,or "bastard" thread. I made a pin that fits fairly snug in the ones I've worked on that is .352 x 14,which is VERY close to 9mm,which in decimal form comes out to .3546.
I've seen 2 variations on Excalibur cues. The gray/silver ones found at sporting goods stores or Wal-Mart usually have a steel collar on both joint faces,and those are 5/16-18 as previously mentioned. I've also seen a solid black "graphite" model that looked to me like a re-branded CueTec,and the pin in it was identical to the standard CueTec. Tommy D.
