I suppose "Leadscrew" is appropriate for those who have never used a leadscrew to cut the lead into a screw blank, or, who have never really thought about it much.
I like clamp screw, and I see that Wilton calls it a spindle. Pressure screw might work as it applies consistent pressure.
Feedscrew doesn't apply unless one is feeding continuous movement, as in facing on the lathe or feeding a workpiece to a milling cutter.
If one thinks about the actual meaning of the words the etymology can be discovered.
Since the title of this thread is "Everything you need to know about bench vises" the correct nomenclature might seem important.
Yost just calls theirs the "Screw", Reed, a "screw" Interestingly, Sears calls the long slide portion of a conventional bench vise the "Engine" (????).
Autospeed, an importing company, also calls it the spindle on their imported Asian vises.
My very limited research shows about equal use by vise manufacturers of both "spindle" and "screw". Since most vises have several screws in them I don't like that one, and a "Spindle" is even less descriptive than "Screw", since in many machines a spindle turns constantly during use while what I call a clamp screw in a vise only turns when it is being brought into working condition, then stops turning.
The spindle in a drill press typically has no threads at all, and that is the most common type use of the term from my experience.
In the end the manufacturer can call it whatever they want to, but it seems to me that a standard term should exist out there someplace, but it sure doesn't seem like leadscrew fits to me.

but there is also Leinen, York, Heuer....
