I would have to measure the tuner lugs to make sure what I am about to say is right.
My inclination is they are not made to be concentric--they don't need to be. The axis of the threads may not line up with the axis of the OD of the pins. Tuner lugs are not driving the wheel on the OD of the pin.
The taper of the tuner pin may not match what the taper in the hub adapters is--90 degree in Trigo and 60 degree in Vintage. From the post you can see I measured Trigo pins in the rather strange 76 degree area--not standard from anything we are used to here.
Tuner pins do not hold the OD to any specific tolerance--it can vary widely leading to stuck pins in the wheel holes.
Hope this helps. I am happy to try again if need be.
