For my 2001 AWD I used Raybestos 816-4253 from Amazon.
DORMAN 615-220 is also fitting (O'Reilly).
Deformed Thread M20-1.50 Hex 30mm
Amazon listings for auto parts have a stupid setup, it's hard to find what you need:
I usually click on a random item like "spindle nut". It will say it doesn't fit may vehicle, but then I have the option to click to see what it fits!
Sometimes I go on rockauto and cross-reference what I need from there.
As for reuse - see the pic below. The tread is deformed at the end, and installing it on will bring it back to "round", exerting pressure on axle treads. When removed, it will remain "round", it will not come back to the original deformed state by itself. So, at the second use, even if torqued the same, it will not grip the treads in the same way.
Sure, it might "work". Backing up just a little bit it won't let the wheel fly. But it will unload the brand-new bearing inside the hub and the hub will fail soon after that.
Usually people end un replacing hub after hub and blaming the hub manufacturer for that - all this for not using a new $5 nut.
