Same here with my tube rings.

Simple Tube Rings!

I mount one scope on top of the other by mounting one set of tube rings on top of the other.

All my tube rings have different threads Unbelievable!
Not only in diameter and thread count but imperial to metric as well.
The 2 sets of rings I use now have 3 different bolts in them.

I've just found this frustration myself two nights ago.

I paid $150 for a Feldstein #6 adapter, which is a Takahashi adapter designed specifically to be bolted on to an STL-11000M and the other end on to the end of the FSQ-106. It, therefore, negates the use of using thumbscrews on adapters.

I finally got a chance to install it on Friday night. Come nightfall and I go to focus for the first time, what do I find? I don't have enough backfocus in the focuser drawtube to come to focus! I fell short by about 1.5 cm. ARGH! $150 down the drain, or, rather, I now need someone to create me a spacer/ring which will give me that extra 1.5-2.5 cm. Frustrating, to say the least.
