Commonly called sheet metal screws you can find screws of this type on our self tapping category page.
Difference between sheet metal and self tapping screws.
They both have a sharp end to fit in the metal.
Self tapping screws are usually designed for metal materials.
Hopefully this gives you a better understanding of the differences between metal and.
To recap metal and wood screws share several common characteristics.
Self drilling a screw that can well self drill through various gauges of metal materials without predrilling.
Self tapping a screw for securing thinner sheet metals and other substrates that cuts its own thread but usually requires a predrilled or pre punched hole.
If the tip is flat it is thread rolling rolling or extruding threads and creating zero clearance between screw and material.
And they are even available in the same materials.
Here are the differences between both fasteners.

Type a self tapping screws are exact matches to standard wood screws except that they are always fully threaded while wood screws are not.
Self tapping screws tap their own thread so they need a pilot hole slightly smaller than the screws diameter.
