You can find one online at many different stores. You can try www.precisionscrewthread.com or www.Ball-Screws.Industrial101.com. Ball Screw thread is very advanced and complicated technology. For getting ball screw thread you will need good and advanced CNC machine.
when lead of the screw is equal to the pitch it is called single threaded screw
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 angle of a thread of a screw is an angle between the threads and it is the defining factor for the shape of the screw thread.
Fine Thread and Course 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.

it is what allows the screw to grip into the material its being screwed into. a screw without a thread is a nail
The screw sizing guide provides information on the different types and sizes of screws, including their length, diameter, and thread pitch. It also includes details on the materials they are made of and their recommended applications.

acme thread
Yes, a parallel sided screw thread is in effect a worm gear.
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.
The ANSI B1.11 Microscope Objective Screw Threads standard covers the single screw thread size: 0.8000"-36 AMO. The standard lays out the screw thread parameters and the parameters for screw thread gauging. There is some mis-information published on the web related to this screw thread which is corrected at this webpage: http://www.ring-plug-thread-gages.com/ti-spec-ANSI-ASME-B1.11.htm
