The nut on the right in the attached photos is a 2018 CR-V EX Honda works nut and the (higher) one on the left is a DP accessory nut. As you can see from the photos, the seat design is different. Factory nuts have a wider and rounder shoulder compared to DPA nuts, which are tapered and have a slightly narrower seat. So they screw on well and definitely tighten as you would expect, but I'm not sure they would fit as perfectly. The time will show.
