Put the screw side up and you don't need the magnet.

Hi Jim,

How about screws (see photos).  These #8 Sheet Metal Screws work about as
good as anything I've tried.  After all is done, I can come along with a
little stick magnet to pull them out.  If they happen to be adhered a bit,
a little tap releases them.  And, since they are recessed a bit, I don't
have any issues with chipping, etc.
