pitch = 1/Threads per Inch
So for a 1/2 - 20 thread the pitch is .1
when lead of the screw is equal to the pitch it is called single threaded screw
Metric size #6 shank, 32 is thread pitch per inch. The bigger the no. the bigger the screw size.
acme thread
Ah, the space between the threads of a screw is called the pitch. It's like the rhythm of a song, guiding the screw as it moves through a material. Just imagine each thread as a happy little tree, dancing along the path set by the pitch.
A thread gauge is a tool used for identifying the particular thread on a bolt or screw. The gauge will have several blades with saw like teeth of different sizes. You match a particular gauge to the thread which will then tell you what size thread it is. gauges come in various pitches to match different screw threads. UNF, UNC, Whitworth, Metric etc. Each has a different pitch angle and thread per inch or millimetre.An image of a thread gauge can be seen HERE
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.
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.
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.
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 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..
