heater cover 'bolts'

[Victor Hughes <v.hughes@student.canberra.edu.au>]

Under the bonnet (hood), on top of the plenum chamber (don't know what
Americans call that) there is a small cover over the heater box.  My
question is: What is the correct head type for the 8 small bolts that
secure this cover.  I thought that they were normal (not phillips) screw
heads with a rounded (pan) profile but I can't find any like that in my
collection of bits.

Thanks
