wheel bearing lock nuts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just picked up a set of wheel bearing lock nuts for the front spindles on my k-20. I don't have a thrust washer in new set or in the can that I dissasembled with all of the old parts. The one used to set against the outer bearing cone and then the nut goes against that. Since the nuts are hardened, are they the thrust surface and there is not a washer???

The inner nut has a small pin for the lock ring to set over and they have 4 slots on the outside for a wrench. then there is an outer lock nut.
I assume the inner nut is also the thrust surface for the bearing since it is hardened?

Anyone know for sure??
