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?

Dull 1' wood chisel makes a good wrong tool for the job.
