Some of them do. These ones don't. You need to install a cage nut behind the screw. I have to do the same thing for the actual Proliant 3000 Server.

The cage nuts I use are M6 threaded and the thumb screw fits perfectly.

I hate to have the ruin a good part to get the screw off (which is why I was asking if anyone has anything lying around) but I agree that may be the only way to get a replacement.
