Some Clarity Questions

Ok just so I'm clear on something, Which ranged weapons in BG1 (both Vanilla and EE) and BG2 get to use the characters STR modifier to enhance their damage?

For example, does the dwarven thrower in BG2 get to use the +2 str damage bonus from 18 str? If so, what about To-Hit modifiers. Does it then use str for that? Or, since its ranged, does it use dex?

Thanks in advance for any clarity.
