Abstract
A self-drilling, anti-burr, threaded fastener is provided having at least two different thread portions. The first thread portion extends along the tip and the second thread portion extends along the tapered portion adjacent to the tip. A third thread portion can be provided between the first and second thread portions that includes a plurality of axial gaps that extend to the thread root to remove burrs. Alternatively, knurling is provided in an area where the first and second thread portions meet, and the knurling acts to remove burrs.
