Zusammenfassung:SELF-TAPPING SCREW WITH ROLLED THREAD TURNS, ON WHICH THE ANGLE BISECTOR OF THE THREAD TURN FORMED BY THE LOAD FLANK AND THE REAR FLANK SLOPES AWAY FROM THE SCREW HEAD AT ANGLE TO THE PERPENDICULAR TO THE SCREW AXIS, THE LOAD FLANK RUNNING IN A STRAIGHT LINE TO THE THREAD ROOT, AND THE REAR FLANK INITIALLY EXTENDING IN A STRAIGHT LINE FROM THE THREAD TIP AND, AT ABOUT 1/3 OF ITS HEIGHT, MERGING VIA A KINK INTO A STRAIGHT ANGLED PORTION AT AN ANGLE THAT IS GREATER THAN THE ANGLE, MEASURED RELATIVE TO THE PERPENDICULAR, OF THE REAR FLANK AND IS BETWEEN 30° AND 50°, THE RATIO OF THE THREAD'S CORE DIAMETER TO THE THREAD;S OUTSIDE DIAMETER BEING GREATER THAN 0.7 AND THE RATIO OF THE THREAD PITCH
