No.4 Hex Self Tapping Screws Type C (AB) ISO 1479 (DIN 7976) in A2 Stainless Steel

Self tapping screws are normally used with sheet metal and plastics. This variant has a hexagon head, so is designed to be driven in with a standard spanner or ratchet and socket. As the name suggests, this type of screw forms its own thread as it is installed into a pre-drilled hole.
