Trapezoidal threaded screws, nuts and bars

The Trapezoidal Thread is shaped like an isosceles trapezium. The thread pitches are broader than in threads with a triangular profile. Trapezoidal Thread are used in lead screw (e.e. for lathe or spindle presses) because they are able to transmit higher axial forces. The flank angle is 30°.
