Thats too funny
I have wondered about that myself
I have 6 slotted flathead and 6 philips flathead screws in #8-24 that fit my big LeMans gascap nicely. I am going to use the philips as I like the fact that the driver is less likely to slip and that all screws on my dash and windhshield with all of its hardware are phillips as well.
The slotted don't look right.
What is right? Not that it will change what I use ...
