M4 Six Lobe or Torx Pan Thread Rolling Screws DIN 7500 Type PE in Bright Zinc Plated (BZP) Steel

Thread rolling screws are designed to tap their own threads into pre-drilled holes in light metals and steel. The triangular shaped tip design allows the thread rolling screw to cold form the female thread into the work piece, so there is no need to pre tap the hole. These items are manufactured to DIN 7500, a standard that covers several head and drive types, including the torx pan head in this section.
