Thread forming screws for plastics are trilobular (featuring a slight triangular shape at the tip) thread rolling screws with extra wide spacing between the threads and a twin lead thread. They're commonly used to engage with plastic materials without a need for a nut on the back end.

Their sharper thread profile increases holding strength while eliminating the material displacement found when using thread cutting screws.
