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?

A larger screwdriver?

You could carefully drill the head off, if it is really mangled. Just
enough into the bolt shaft so it comes out with the nut via the
bottom.

Can you get needle nosed vise grips on the head to hold it.
