Lug nut /stud length

Okay, so Yukon gave me a .662 dia spec for the knurl, at 33/64's long (weird length)

Problem is I can find narry a stud at Summit or JEGS with that dia.

The confusing part is that they do list some Mopar studs at .622 dia. ??? Could Yukon have misprinted their own spec?

Maybe I should start a new thread on Yukon wheel studs as I can't be the first one to encounter this. Someone must have worked out a fix by now?

Anyone??

Thanks.
