Nice write up, but you skipped right past the reason Acme threads exist. The most precise and repeatable thread to drive a load with minimal backlash (as desired on machine leadscrews) is the square thread. You’ll see square threads on all early 20th-century American machine tool leadscrews. However, square threads are very difficult to make, because the cutting tool has no relief area; the sides of the tool will bind up as the thread gets deeper. Acme was created as a compromise. It provides just enough angle to give cutting tool clearance during manufacture, while still mostly retaining the desirable properties of a square thread for driving a load.

In addition, engineers can design the joint to limit exposure to electrolytes. For example, screws should be driven into blind holes instead of through holes, so the tip of the fastener is not exposed to the environment. Clearance should be provided around the fastener head to permit drainage. The fastener can also be paired with a washer made of aluminum or a nonconductive material.
