It is called simply "threads per length" . In US it is threads per inch. It is the reciprocal of the pitch. For example a screw with 32 threads per inch has a pitch of 1/32 inch. The pitch is distance between threads
As I recall , 3 full threads is minimum engagement length
The pitch of a screw thread is a measure of how closely the threads are spaced. It can be expressed as the number of threads per unit length (32 threads per inch, for example) or as the distance between two threads ( such as .8 mm).
§ Screw threads have better compression strength than other threads. § Due to low thread angle there is no radial pressure on nut. § Due to smaller angle, the lead of screw is less.
The mechanical advantage of a screw is given as MA = circumference / pitch. The pitch of the screw is the number of threads per centimeter. The circumference is measured at the working portion of the screw, not the head.
It is easier. The question is not complete enough to be answered. The word EASIER needs to be further defined. so the question should read: What is easier to [add information here]; more screw threads or less screw threads?

the threads determine the depth the screw should move

The hole that you put a screw into is referred to as a "tapped hole". The rib-like things in the hole are called "threads" or, more specifically, "internal threads" as opposed to the external threads on a screw.
Threads.
pitch
A "screw pitch gauge" is used to measure screw pitch. Typically, the gauge has a number of indented templates for each standard pitch. Matching a particular template to the screw or nut gives the pitch. You can also use a measuring device (ruler, micrometer, etc.) to measure a group of threads and then "do the math" to estimate pitch. Accuracy depends on your ability to accurately measure length and count threads.

To determine the size of a screw, you can use a ruler or a caliper to measure the length of the screw from the tip to the head. Then, count the number of threads per inch to determine the screw's thread pitch. This information will help you identify the size of the screw.
The distance between two threads in a screw is called the pitch. It is the measurement of how far the screw advances with one complete turn.
The distance between threads of a screw is called the "pitch." Pitch is defined as the axial distance between corresponding points on adjacent threads, essentially measuring how far the screw advances with one complete turn. It is typically expressed in millimeters for metric screws and in threads per inch for imperial screws.
