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).
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
§ 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.
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?
knuckle threads are used in railway carriage couplings.
no

A screw thread consists of a continuous triangular prism (the thread) wrapped in a spiral round a cylinder. A screw thread may be used to elevate an object in a manner analogous to an inclined plane.
a screw with closely spread threads
the threads determine the depth the screw should move
A micrometer typically has 40 threads per inch on the screw, which means it has 40 pitch threads along its length. This allows for very precise measurements to be taken with the micrometer.
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
A screw that screws into a screw works by using its threads to grip onto the existing screw and create a secure connection. The threads on the screw being inserted match the threads on the existing screw, allowing them to twist together and hold in place.
screw thread are single threads which means they are not double
A screw is a fastener that is similar to a nail, but it has threads.
Assuming it is the LENGTH of the screw that is 1_7/8: (2/3 * 1.875)/16 = .078 inches
Screw sizes are typically given as a combination of a diameter and a length. The diameter is usually measured in millimeters or inches, while the length is measured in inches. For example, a screw size of 4-40 indicates a #4 diameter screw with 40 threads per inch.
