Peter,

That screw is a weird size like maybe 3-56.  I don't think you'll  
find it at Home Depot.  If you can't get to a decent repair shop to  
buy a Bach screw, you may be able to slip a piece of paper between  
the shaft of the valve and the stop arm and force the arm on so it  
stays put.  I think it will work, it's worth a try.
