Which term describes the distance between corresponding points of adjacent threads?

Explanation:
The distance between corresponding points on adjacent threads is called pitch. Pitch is the axial spacing from one thread crest to the next crest, measured along the screw’s axis. For a single-start thread, lead equals pitch, while for multi-start threads the lead is pitch times the number of starts. The other terms describe different aspects: diameter is the thread size, the angle is the thread’s shape angle, and the number of threads per inch is a density measure that is the reciprocal of pitch in inch-based threads.
