DIN 7981 Stainless Steel Pan Head Phillips Self Tapping
DIN 7981 Stainless Steel Pan Head Phillips Self Tapping Screw. A self-tapping screw is a screw that can tap its own hole as it is driven into the material. For hard substrates such as metal or hard plastics, the self-tapping ability is often created by cutting a gap in the continuity of the thread on the screw, generating a flute and cutting edge similar to those on a tap.
