is it a plain black cast iron door? if so after installing the new screw and clip, push a little rutland stove cement in the hole on the outside, heat it up with propane torch until the outside is hardened then gently scrape to mimic the texture, repaint right over the rutland, if its done well you wont even see the repair, the screw will seal the hole anyway so its not a danger.
and when regasketing in the future these 2 tips: first, WD-40 is your friend before and a little spray graphite after to help the screw from reseizing for the next time right before you put the screw back in. and second, never use power tools on door screws always use a wrench to gently minister the screws out.
Spray graphite? I used the power drill to drill the piece out that was in the hole still from the head of the screw popping off. At any rate I ordered a new door and will keep the old one as a back up and try to fix it.
