ISO Metric Thread profile
The Major Diameter is the largest diameter on the thread and is measured from the thread crest to crest (peak of the thread).
This is the distance (mm) from one thread to the next, this can be measured from tip to tip or groove to groove. Pitch can also be defined as TPI, which stands for threads per inch.
Minor Diameter is the smallest diameter on the thread and is measured from the thread root to root (Bottom of the thread).
The angle between the thread faces. 60 degrees in the example above.
The thread will assemble when rotated clockwise. "righty tighty lefty loosely"
The thread will assemble when rotated counter-clockwise.
