Don’t quote me, but if I remember correctly, that is the larger size where the center is more solid like an elliptical half oval that extends nearly to the tip and the fins of the cross are attached. I think it also has the four Pozi minor points at 45 degrees from the cross. It has more of a spline like structure rather than the four pointed cone of a typical Phillips. That tip won’t fit any other Phillips cross. I have only used them a few times, but have had many driver sets that include them. These type are usually tossed in my misc tools drawers because accidentally grabbing them is annoying…
