Pretty sure the end cap doesn't butt against the hex screw. The hex is fixed to the axle, the end cap is fixed to the body. If they touched, there would be friction. It does look like WT is using the end cap to help hold the outboard bearings snug in the body, by pressing against the outer races (hence the two lengths of end caps to match the 2 body widths), but it's not going to be touching the axle-fixing bolt.
I do wonder if WT's use of left-hand threads on the right-side fixing bolt is going to greatly eliminate loosening of that fixing bolt... That might be the most important difference to the OG Atlas, because there is certainly a chance that most/all of those broken Atlas bolts only broke because they were already loose.
