Yes, the pan head phillips head screws tapped into the steel frame.
The worst is the screw inside the door well holding the front fender flare, since you can't get to it straight on. In that case, I had to cut the plastic to the expose the screw then cut the screw off. I then reamed the hole slightly bigger and attached the new wider fender flare with pin plugs.
Here is a good hint. When installing the nerf bars, the same screws hold the plastic rocker panel under the door. Having just messed around with the fender flares I was very pissed off, because the screws would not come out of course. So I took a light and magnifying glass and was barely able to discern dimples on the outside of the panels to locate where to drill the 1.5" holes for the nerf bars. In other words, I didn't need to remove the racker panel. It worked just fine. That saved me a lot of frustration and cursing!
The other location I had to deal with this stupid screw was on the rail behind the seats when installing a SuperAtv rear windshield. At least this was accessible and I got it out using a old fashioned hammer impact screw remover. SuperAtv provided hex-head screws instead, which is what Kawasaki should have used to begin with.
