A cosmetic thread is a cosmetic feature that represents the diameter of a thread. Unlike other cosmetic features, you cannot modify the line style of a cosmetic thread. If the surface is similar to a hole found in the tables, the selected surface’s diameter is matched to a thread in the standard tables.

Keeping this in consideration, Why do screws have different threads?

Finer threads are stronger as they have a larger stress area for the same diameter thread. Fine threads are less likely to vibrate loose as they have a smaller helix angle and allow finer adjustment. Finer threads develop greater preload with less tightening torque.
