Anybody know anything about machine screws? What is a "binder" machine screw vs a standard?

I'm ordering some nylon machine screws to use in a project, I see options for "binder" machine screws. What is a "binder" vs a standard machine screw?

Example:

It refers to the type of head:

"The heads of binder head screws are about 10% larger in diameter than those of pan head screws"

So there's no functional difference in thread pitch or anything like that, it's strictly the head? Doesn't seem that different from a pan head...

Ahh that makes more sense.

Guess binder is what I want then, if I can find them in M3.

Thanks for the help.

4th item down - Binding Head

Head Styles

Today it is considered obsolete, replaced by modern 'Pan Head' (Item # 1)

It's only the clamping characteristic of the head design where it mates to a surface.

Maybe that would explain why people selling "binder" don't have metric sizes.

Oh and holy crap google is fast, I just searched for "m3 binder nylon machine screw" and my thread was the top result.

I just bought a bunch of smaller nylon stuff for an Abit IP35-Pro heat pipe mod, from Amazon seller Small Parts. They delivered in about 7 days, didn't require an account, and it was quality stuff.
