I need to tighten my toilet seat plastic bolts. The nut below the toilet is
manageable but the 'bolt' that extends into the seat hinge is slotted and
any screwdriver I have just mangles the plastic. I tried a putty knife but
it is too wide to get into the inset the bolt head sits in. How do plumbers
do it without damage?

Grind an old putty knife down so it fits. Realistically you should
just be holding that screw and running up the nut from the bottom
anyway.
