The packaging says 'Countersunk Allen Bolts' so that'll do me.
I know set screws as grub screws so I'm with Steve.
The difference between a bolt and a set screw is that there is thread the entire length of the set screw, whereas a bolt is only partly threaded. So, an allen bolt would not be fully threaded. Just to confuse a grub screw can also be called a setscrew.
The other common name for allen bolts/screws are socket screws.

The tube manual is quite like a telephone book. The number of it perfect. It is useful to make it possible to speak with a girl. But we can't see her beautiful face from the telephone number
"Set screw or setscrew in the UK refers to a bolt which is fully threaded, with no smooth shank. These commonly have a hex head, but are also found with socket or screw heads."
Which is what I said.
Different in USA.

Thats a fair cop phil
My first job was at Marconi, and every electrical apprentice had to go through the workshop training program. That's where I learned workshop practice including drilling, lathe work, welding etc. Even the proper way to use hand tools. Hardware terminology has stuck with me, even after 50 years.
