Axle Lock Nut Specs?

I need some axle lock nuts and found these on the web:

1. 5/16-18 NYLON LOCK NUT
WRENCH: 1/2" - HEIGHT: 11/32"

2. 5/16-24 NYLON LOCK NUT
WRENCH: 1/2" - HEIGHT: 11/32"

Does anyone know for certain which of these two different specs is used for truck axles? Is it 5/16-18 or 5/16-24?

And in case someone asks, I've learned that special 8mm axles are still milled with the standard 5/16th threading. It's mixed and matched so the specialty axles still use the standard nuts.
