Self drilling screw description:

Similar to a sheet metal screw, but it has a drill-shaped point to cut through the substrate

to eliminate the need for drilling a pilot hole. Designed for use in soft steel or other metals.

The points are numbered from 1 through 5, the larger the number, the thicker metal it can

go through without a pilot hole. A 5 point can drill a 0.5 in (12.7 mm) of steel, for example.
