First sentence: A parallel screw thread is a continuous helical ridge of uniform section and uniform axial spacing formed on the exterior of a circular cylinder or on the interior of a circular hole such that the axial displacement of a point which travels along a helix connecting corresponding points of successive ridge profiles is always proportional to its angular displacement about the axis.
