  The trapezoidal thread's cross section is an isosceles trapezoid with an angle of 15°. The flank angle is 30°. The trapezoidal lead screw has a larger diameter and greater pitch than standard threads. The pitch angle is smaller than the arctangent for single-start trapezoidal lead screws. This results in self-locking. Two-start lead screws, in contrast, are not self-locking.
