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).
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.
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
it is what allows the screw to grip into the material its being screwed into. a screw without a thread is a nail
when a spiral groove is cut over a hole, then it is nut thread. when a spiral groove is cut over a shaft, then it is screw thread.
There is a small set screw on the side of the die itself. It all depends on the die being either a thread chasing die or not. Thread chasing dies are used to restore old threads and can't be adjusted. The set screw can be tightened or loosened accordingly to match the thread pitch.
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..
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
The standard size and thread pitch of a camera mount screw is 1/4"-20.

The IMA (ideal mechanical advantage) of a screw is determined by the ratio of the circumference of the screw head to the pitch of the screw thread. The formula for calculating IMA is 2πr/p, where r is the radius of the screw head and p is the pitch of the screw thread.
Screws have three main dimensions: diameter, length, and thread pitch. The diameter is the measurement across the screw shaft, the length is how long the screw is, and the thread pitch is the distance between each thread on the screw. These dimensions determine the size and compatibility of the screw for different applications.
Thread
The standard size of a camera mounting screw is 1/4 inch and the thread pitch is 20 threads per inch.
The dimensions of an M3 screw are 3mm in diameter and the thread pitch is 0.5mm.
The dimensions of an M4 screw are 4mm in diameter and the thread pitch is 0.7mm.
pitch = 1/Threads per Inch So for a 1/2 - 20 thread the pitch is .1
