None of the above is absolutely true.
Consider machine screws. Consider phillips head 1/4-20 bolts. Tell me you've never seen a toggle bolt with a slot or Phillips head. Look at lag bolts...they have points and wood threads instead of machine threads. Sheet metal screws frequently have hex heads.
You can be mostly right if you apply some of the characteristics, but as soon as you say "it's this and only this" I'll give you an example that contradicts.
Generally speaking, bolts will have hex heads with machine threads (but again, I've listed exceptions already) and screws will have a slot or Phillips (sometimes square) head and broad (sheet metal/wood) threads and a point.
Mostly, it's what they're commonly referred to wherever it is you're speaking of them. What's a bolt to one may be a screw to another and neither would be wrong...generally :)

A BOLT has threads and a flat tip at the end. It can have either a screwdriver-type head or hex head. A SCREW has threads and a pointed tip at the end. The reason why it is called a screw is because a screw can be drilled (screwed) into something. A bolt can't.

a bolt goes through a hole wider than the bolt and the teeth on it, it is fastened using a nut on it's opposite end in order to remain in place.
A screw on the other hand needs threads in the hole in order to remain in place, it does not need a nut on it's other end.
Machine screws have the hole that they need to go into pre-tapped (ie, it has been pre-threaded using a "tap"..a tool which creates threads in a hole, so that it has threads which the screw can fit perfectly)..Self Tapping screws are steel screws which create their own threads when you screw them in. Wood screws are similar, although they only work in wood reliably.
a thread refers to the grooves which the teeth on the screw fit into in order to fasten correctly.

Bolts often have rounded nobby looking heads that stick out of whatever they are being put in. Screws are flat on the heads adn when screwed in are flush.

Bolts are flat on the end and screws are pointed. (That's coming from the guy I asked sitting beside me...)

A bolt threads into a nut whereas a screw threads into the material to be fastened.
