Screw — definition & meaning
Word Type Definition Screw n. 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.
