#4 Thread Rolling Screws (ASME B18. 6.4)

Thread Rolling Screws, also called Swageform Screws or Plastic Screws are designed to be screwed into a pre-formed hole in plastic. The form of the screw thread is such that the plastic is deformed by flowing around the thread rather than cut, and leads to a secure joint.
