That's what I do, and I use my fingers for the nut.

That's on my own toilet seat. *If it were someone else's, I make him

Not that the nut itself is dirty, but your hand could conceivably get
dirty.

This particular toilet seat, a Bemis, did not have a screwdriver slot.
Instead, it fastened by threaded rods, which were screwed into the
metal hinge pieces from below, and tightened in place by the plastic
nuts. When new, the rods kept loosening in the hinge pieces, with no
good way to tighten them; when the metal hinge broke, however, they
had rusted or corroded into place. In my cramped bathroom, with the
toilet I have, it is very difficult to grasp the nuts from below by
hand or with a Vise-Grip.

It turns out that there are a couple of wrenches on the market
designed to fit the plastic nut. I got one at Home Depot, but its
well does not go deep enough for the unusually long threaded rods that
came with the Bemis (the others I found on the Web seem to have the
same problem). I wound up having to cut the rod with a hacksaw just
below the hinge hardware. But the toilet seat wrench I bought was
very helpful in installing my new toilet seat.
