Yes, these are the flat, squiggly hammered-down clips which help keep the subfloor together. I wouldn't think of removing them, but I'm faced with the goal of as flat a floor as possible on which to lay my engineered wood/laminate flooring. The thin foam pad may take care of some very small deviations in my subfloor, but the tops of those clips all over the floor is troublsome. If there's steel under the plywood seams, then that explains the clips stubborn nature. My next option would be to grind down the tops of them--that would leave me with a flat floor.
ps. And thanks to PeterH also! That makes sense...
