What is a 16 thread?
The number of threads you have depends on the number of cores in your CPU. Each CPU core can have two threads. So a processor with two cores will have four threads. A processor with eight cores will have 16 threads.
What pitch is a 1/4 20 thread?

What pitch is fine thread?
1.25mm
Understanding Inch & Metric Thread Callouts
25 (fine) thread has a 1.25mm pitch. To simplify metric thread callouts, the international (ISO) standard for metric threads eliminates the pitch callout on coarse threads.

What thread is 26 TPI?
All sizes 1⁄4 inch and larger use 26 threads per inch (tpi), making them similar to 1 mm ISO threads, which are 25.4 per inch and also run at a 60 degrees angle. It was originally used with both bicycles and motorcycles. However it is now believed to be obsolete in motorcycle manufacture.
What is meant by m8x1 25 thread?
For metric fasteners, you will see a M8 x 1.25 or an M8 x 1. For thread pitch, the distance between two points is the second number meaning the higher the number the fewer threads there are. This means the M8 x 1.25 is the coarse threading and the M8 x 1 is the fine thread.

What thread pitch is?
Thread pitch is the distance from the crest of one thread to another crest measured along the length of the thread. Pitch is best measured using a thread pitch gauge. So-called “English,” “Standard,” “Imperial,” or SAE threads are designated by the frequency of how many threads are counted along one inch.
