| titleOfInvention | Thread forming screw with independent thread spirals and different thread flank angles |
| abstract | The invention relates to a thread forming screw, comprising: a shank (10) which has a tip (11) in the front region of the shank for insertion into a hole in a base and a drive element in the rear region of the shank for transmitting a torque to the shank; a spiral groove; and a threaded screw (30) inserted into the helical groove, wherein the helical groove has a front flank (20) and a rear flank (22) opposite the front flank. According to the invention, the front flank has at least partially a thread flank angle different from the rear flank. |
