Pin diameters

[Master of None]

Need some basic information for shaft joints.
1. Mezz United speed...what is the diameter of the speed (nose) insert? The rest of the pin is 5/16-14
2. Viking QR...what is the diameter of the speed (nose) insert? The rest is 5/16-18
And no I don't have access to the butts. I'm building shafts and don't want them coming back because they don't fit.
Thanks

I have a Viking on hand. The nose of the pin is .26 to .262 inches in diameter.
