Screw threads can be categorized into various types based on their design and application, including external threads (on screws or bolts) and internal threads (in nuts or tapped holes). Common thread forms include the Unified Thread Standard (UTS), metric threads, and ACME threads, which are used for different mechanical applications. Other variations include left-handed threads, which tighten in the opposite direction, and square threads, often used in lead screws for linear motion. Each type serves specific purposes in engineering and manufacturing, ensuring optimal performance and compatibility in assembly.
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.

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 helix angle of a screw thread is the angle formed between the thread's helix and a plane perpendicular to the axis of the screw. It is determined by the pitch of the thread (the distance between adjacent threads) and the diameter of the screw. A larger helix angle generally indicates a coarser thread, while a smaller angle corresponds to a finer thread. This angle is crucial for understanding the screw's mechanical properties and performance in applications.
