It refers to the diameter of the screw. More precisely, it is a 0.138" diameter screw. You can get it in with various head style and thread pitch.
It means that there is .5mm from a particular spot on one thread to the corresponding spot on the next thread
If you mean 'Screw Thread' I will give examples, but first understand that the word screw is a process. It is something you can do. We often say 'Screw these pieces together'. Now some examples :- Top of a toothpaste tube with a screw on lid. top of a jar of food with a screw on lid . A screw thread inside a water tap handle. Most common of all of course is a wood screw, and a metal thread screw or bolt.. Also the screw thread on the cap of a bottle of soft drink.
the 'thread'.
A thread angle is the angle of the threads relative to the shank which is 60 degrees for unified screws The lead angle is the pitch of the screw divided by the circumference of the shank; it varies but is around 3 degrees
8==> (0)
when lead of the screw is equal to the pitch it is called single threaded screw
the parts of the screw are thread, pitch, and the last is bolt
This is a tool that is used to measure the pitch diameter of a screw. This tool looks like a standard micrometer except that the anvils are specially configured to reach into the screw thread groove and touch the pitch diameter of the screw thread. The screw thread micrometer does not measure any other aspect of the screw thread. It does not measure the: pitch; threads-per-inch; major diameter; minor diameter; flank angles; lead; helix angle.
Thread
pitch = 1/Threads per Inch So for a 1/2 - 20 thread the pitch is .1

Pitch is the distance from the crest of one thread to the next. the displacement of the circular scale due to a complete rotation of the screw, along the main scale is called screw pitch..
what does a standard thread gauge measure
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 refers to the diameter of the screw. More precisely, it is a 0.138" diameter screw. You can get it in with various head style and thread pitch.
The pitch is the axial distance between threads, and the distance the thread moves with a 360 degree revolution. So if the pitch of a screw is 1mm, one revolution will move it 1mm farther down.
