Where did "cheese head screw" come from...except maybe Wisconsin?
Blink! Blink!
I've been living in a fog, or so it seems.
In all my years, I've never heard a reference to a cheese head fastener. And, yeah, it makes sense.

Thanks for the education.

On that subject, that may be what is in the (grinding) wheel hubs I'm going to use with my #2 Cincinnati cutter grinder. They are, no doubt, used on more modern machines, but by removing a snap ring and the screw with the outlandishly large head, they fit my grinder perfectly, and the price was right. They were a part of a large purchase years ago, and there's a couple dozen of them, so I'm well equipped for anything that comes down the pike.

Have drawers full of these things...

pretty sure Jim used them at Springfield Armory back during WWII - specific diameter head that you can put into a specific diameter hole and keep things aligned.
Too many things going on to bother listing them.

Thanks, Bill. I now understand they are much like a pan head, just smaller in diameter. How did I miss that for so many years?

The screws I mentioned, above, are not even close. The head is huge, so they must be designed specifically for the product in which they are used.

And, having looked at the McMaster site and not seeing a "cheese head" screw, with a recessed hex socket, I withdraw my previous comment!
