Phillips Csk Self Tapping Screws Type C (AB) ISO 7050 (DIN 7982H) in A2 Stainless Steel
Self tapping screws are normally used with sheet metal and plastics. This variant has a countersunk head with a phillips pattern drive. The countersunk head is typically used in conjunction with a countersunk hole providing a flush, snag free fit. As the name suggests, this type of screw forms its own thread as it is installed into a pre-drilled hole.
