Yes, got the lugnut's with the wheels from the tire shop. Looking at the contact pattern on the lug on my desk it looks like it was properly bearing on the wheel.
Weird deal as I've got about 30k miles on the wheels, rotate them ~7500 miles and I rotated them at the beginning of the summer so have put quite a few miles on them before this happened.
There have been a lot of bad places this could have happened, so I'm actually very thankful it happened where it did, when it did. Much rather be standing on the side of the road in the sun than the side of the road at -20 in the dark.
