Back before carbon fiber and R360 LD when Cuetec only made the SST fiberglass coated shafts, what was the (then) standard thread size they used? I believe it was considered proprietary at that time.
That is pretty much correct, but the new pin is very tight on the old shaftsI had older SST, 8-9 years ago. 3/8x14, same as the new ones. The joint diameter of the older is smaller, maybe 20mm. I think the new ones are 21.30mm. If someone knows different please correct me.
Correct. Same pin, different joint diameter. The older joint diameter is referred to as the legacy joint diameter. It is 20mm (.787 ish).I had older SST, 8-9 years ago. 3/8x14, same as the new ones.
