Linear actuators are compact electrical devices that output high force using simple DC motors and gearing. I'll tear it down and show you what it's good at and why it's terrible in industrial applications.

8 threads per inch on a smaller diameter would result in a steeper inclined plane angle, and thus less clamping force but higher linear speed for the same input, yes?

Hmmm. Maybe. Let's check by turning the screws into wedges. pi D x 8 3.14 x 8 say 25 inches run over 1" rise. vs. 0.5x 3,14 x 8 12 inch run over 1" rise.
Change the torque to force: 1 in lbs / 0.5" 2 lbs on a thin wedge. vs. 1/0.25" 4 lbs on a thicker wedge.
YES, I think you are right. But the final guestimation would turn out as a wash factoring in the friction fudge factor.Thanks for pointing that out!
