I have looked all over and even called the Honda dealership and cannot find the size of this one screw that attaches the edge of the front bumper cover up under the fender. It took us forever to get the new bumper into place which involved putting the one screw into the other side, so I can't take that one out to size it up, when we realized that the second screw was missing. It just takes one screw on each fender and the rest of them were just plastic clips.

Any help would be amazing....my car is a 2004 Civic Hybrid

im not sure what screw your talking about but if its a self taping screw then just get a stainless steel one at home depot this ain't rocket science as long as it fits use it.
