Is this the radiator bleed screw?

Yes!
It is a little shorter than the original bleed screw. 
Don.
You have no idea how happy you have made me. My know it all neighbor, that thinks he knows everything, told me it was not.

Probably owns a Tesla…
The idea of saying it is not the bleeding screw isn’t as funny as to know what he said it is
I can’t wait to know…

me sees it as to be the exact correct size for the old thermostat housings, and to be the original bleed screw
my old thermostat housing (not in the car anymore) has this screw
newer screws for newer housings are longer and equipped with an hexagonal head
My mistake, it looked like someone shortened it and cut the straight slot.

In fairness to your neighbor, your post title refers to "radiator bleed screw." This implies that a "bleed" screw is located on the radiator, rather than a cooling system bleed screw found on the thermostat housing (fig 97). Perhaps . . . "bleed" screw was confused with the radiator "drain" bolt, screw or plug (fig 95).

It's used to wash the front of the engine.
My old 73 and current 72 have the 8mm hex bleed screw, not the slotted one (which appears to be more dicey to remove than the hex version).
No defence for him. He is just a pain in the ass. Everytime I borrow a tool from him I regret it, because he has to lecture me on how to do my project, and go into great detail. Yesterday when I was finishing up the flushing the radiator, he stopped by and asked if I needed to help. I told him no, I was in a rush to complete the job. I was running the engine and started to bleed it with the screw. He freaked out and told me it was extremely dangerous and it was not a bleed. I have decided that I need to got to Harbor Frieght and just buy tools in the future!

II think that would be a good move.
It sounds like you've got your bleed screw loosened up. Mine was stuck and it snapped half off at the slot when I applied torque. I should have been very gentle with it as it clearly hadn't been moved in many years. Locking two nuts onto it would have been a good move after letting penetrant soak in for a while. Now I'll have to replace it with the later version.
Father to son: Can you please ask our neighbor if we can borrow his hammer as we need to do some work in the house?
Son: He says that it is his hammer, and he does not like to share it.
Father: Can you please ask again, we really need it, just for today.
Son: The neighbor says the hammer will wear...
Father: Nonsense, hammers do not wear, can you ask again please, with more urgency?
Son: I am sorry, he refuses to share his hammer with us.
Father: OK, let's use ours then, can you please bring it?
