  The trapezoidal thread cross section is an isosceles trapezoid with an angle of 15°. Theflank angle is 30°. The trapezoidal lead screw has a larger diameter and greater pitch than standard threads do. The pitch angle is smaller than the arctangent for single start trapezoidal lead screws. Thus, self-locking is given. Two-start lead screws, on the other hand, are not self-locking.
