Glossary
Major Diameter
The Major Diameter is the largest diameter on the thread and is measured from the thread crest to crest (peak of the thread).
Pitch
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
Minor Diameter is the smallest diameter on the thread and is measured from the thread root to root (Bottom of the thread).
Thread Angle
The angle between the thread faces. 60 degrees in the example above.
Right-Hand Thread
The thread will assemble when rotated clockwise. "righty tighty lefty loosely"
Left-Hand Thread
The thread will assemble when rotated counter-clockwise.
