Loose Allen Screws inside engine???

Interesting thing happened this weekend. I was installing a new clutch on my 2003 660 and noticed four Allen screws laying in the bottom of the case just below the clutch housing. They appear to have been snapped off and there was only about 1/4 inch of thread. My first thought was from the starter clutch, so I pulled that and everything was in tact. They look just like the 6 screws that hold the starter clutch together. Any thoughts Is there any other internal parts that would also use these screws?

Probably from the starter clutch. If your not the original owner there is no way to verify that it hasn't been tore in to.
