"Button head" is great description of what EM sent me, a long time ago. And yes I'd like to see pictures. You must have a fiber glass replica like mine, if you milled the door surface to sink the ferrule head. Upon testing the magnetic attraction of my button head ferrules from EM seem to be chromed steel. The button head -the nut- and my tool box all seem to have the same attraction.
