摘要

The screw comprises an axial bore (6) allowing its sliding engagement on a guide pin. It comprises distal machined notches in its wall delimiting two radial faces (7) which form cutting edges (8) with the bore. There are two external skin surfaces (9) which together with the radial faces and the cutting edges enable the screw to be self drilling and self-tapping.
