I have a problem... I too thought this hole was just a mounting point and thought nothing of it. My action came without this screw and the previous owner seems to have ruined some of the threads... What to do now?

Retap the threads and clean them up, below is where to get the British type taps and dies.

Screw, ejector = 3BA (Number three BA (British Association) Thread type)

Thanks for your help in a few of my post Edward. I ordered the 3BA Tap and two of the British Fasteners 3BA Cheesehead screws in 1/2 inch to cut down to size. I already eBayed an original ejector screw to use but got spares in case I have problems. I also ordered new Extractor and Firing Pin springs from Midway and a bolt tool (from gunbroker) to make this a completely refurbished gun. Thanks Again
