   1. A cylinder, or a cylindrical perforation, having a
      continuous rib, called the thread, winding round it
      spirally at a constant inclination, so as to leave a
      continuous spiral groove between one turn and the next, --
      used chiefly for producing, when revolved, motion or
      pressure in the direction of its axis, by the sliding of
      the threads of the cylinder in the grooves between the
      threads of the perforation adapted to it, the former being
      distinguished as the external, or male screw, or, more
      usually the screw; the latter as the internal, or female
      screw, or, more usually, the nut.

   Note: The screw, as a mechanical power, is a modification of
         the inclined plane, and may be regarded as a
         right-angled triangle wrapped round a cylinder, the
         hypotenuse of the marking the spiral thread of the
         screw, its base equaling the circumference of the
         cylinder, and its height the pitch of the thread.
