Question
Define the pitch of the screw gauge.
✓
Answer
When one complete rotation is given to the screw hand, it moves forward or backward by a distance is called the pitch of the screw. It is a distance between two consecutive threads of the screw.
Pitch of the screw = distance traveled by screw-in n rotations/n rotations
Pitch of the screw = distance traveled by screw-in n rotations/n rotations
