M4 Six Lobe or Torx Csk Thread Rolling Screws for Metal DIN 7500 Type ME-T 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 countersunk head in this section.
