As Blecktrumman also wrote, it's called a screw! Regardless of the shape of the head or whether they are pointed or blunt, it's called a screw if there are threads. Bolts have no threads! Bolts have a round head, no threads, but instead, at the opposite end, a hole for something like a cotter pin.
Since the use of the original type of bolt you refer to is very rare today, this hardly matters?
The problem with calling everything a screw is that it doesn't distinguish between a joint where you thread into one or both pieces, or one with external locking with a nut.
Possibly, one could call the latter a screwed bolt joint?

I bought a pallet of plastic bags at an auction once.....
When I looked a little more closely, they were bags for carrots, i.e. with holes in them!!
Well, you learn something new every day
