I think they are original equipment and they appear to be stainless steel. I've broken about 4 bits, cobalts and titanium and an ez-out. I tried using a cold chisel on one but only broke loose the nut that is welded to the inside of the door. I've taken that and put it in vice grips and it still won't come loose. I did break off a couple of screw heads, only making my problem worse. What I really need is to figure out how to attach the molding to the door without all this. I've tried the push on trim clips from pep boys but they seem awful flimsy. I'm thinking about finding a plastic wall anchor, gluing the trim clip and shoving that in the hole.
