A drop of thin CA (superglue) works well also.. When the screw is

I used to worry that the CA might fill the screw head but it never
has..

My variation on that theme - I use the Post-It Note adhesive that
comes in the mail. It's used to seal magazine covers and coupon
booklets and keep them closed during mailing, yet has to be easy to
open without tearing the paper. The stuff is a strip, like a bead of
caulk, and it can be rolled up with a finger. It looks just like a
booger and it's as sticky as one, without the grossness involved. It
makes a dandy temporary adhesive blob to hold a screw onto a
screwdriver, and it's easy to remove and doesn't leave any residue.
