Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

What is claimed is:

1. A fastener, comprising: a body having a proximal end, a distal end and an axis, a head at said proximal end, a drilling tip at said distal end, a thread extending radially outwardly from said body, said thread having a first end spaced from said drilling tip and a second end spaced from an underside of said head, and a notch in said body and said thread, said notch having a first end, a second end, a leading face and a trailing face, wherein said leading face and said trailing face are angled about 20 degrees leftward with respect to said axis, said second end is spaced about 4/10 inch from said drilling tip, said leading face is generally concave, said trailing face is generally planar, and said trailing face is generally perpendicular to a plane that is tangent to said body at an intersection of said trailing face and said body.

2. A fastener, comprising: a body having a proximal end, a distal end and an axis, a head at said proximal end, a drilling tip at said distal end, a thread extending radially outwardly from said body, said thread having a first end spaced from said drilling tip and a second end spaced from an underside of said head, and a notch in said distal end of said body and in said thread, said notch having a first end, a second end, a leading face and a trailing face, wherein said leading face and said trailing face are angled leftward with respect to said axis.

3. A fastener according to claim 2, wherein each of said leading face and said trailing face is angled between about 10 degrees and about 30 degrees leftward with respect to said axis.

4. A fastener according to claim 3, wherein each of said leading face and said trailing face is angled about 20 degrees with respect to said axis.

5. A fastener according to claim 4, wherein at least one of said leading face and said trailing face is generally planar.

6. A fastener according to claim 2, wherein said leading face and said trailing face intersect at an edge, said edge angled leftward with respect to said axis.

7. A fastener according to claim 6, wherein said leading face, said trailing face and said edge are substantially similarly angled leftward with respect to said axis.

8. A fastener according to claim 6, wherein said leading face is concave.

9. A fastener according to claim 2, wherein when said fastener is installed in a substrate, said leading face directs a shaving formed from said substrate into said notch and an outer edge of said trailing face cuts said shaving away from said substrate.
