I see on the link that the Exactrail wheels are number EWN-301. I have used these when they were still sold by my dealer in Germany and was happy with them. My main use was replacement of Athearn plastic wheels. The Athearn trucks of the early time looked the same as Atlas, both with Accumates then, but Athearn trucks were narrower and had the shorter axle length.
IIRC the threads were similar to the wide thread FVM wheels. The profiling of the wheel backside is only visible on a few cars, mostly tank cars ( IMHO

)
