Final answer:
The distance of a point on a thread to the corresponding point on the next thread measured parallel to the axis is called the pitch of the thread.
Step-by-step explanation:
The distance of a point on a thread to the corresponding point on the next thread measured parallel to the axis is called the pitch of the thread. The pitch is the distance between corresponding points on adjacent threads along the axis of the thread.
For example, if you have a screw with a pitch of 1 millimeter, it means that the distance from one thread to the next thread, measured parallel to the axis of the screw, is 1 millimeter.
The pitch is an important characteristic of threaded objects, such as screws, bolts, and nuts, as it determines how fast the object can move or how tightly it can be secured.
