Abstract
A combination of deformations on a single nail shank provides a nail with optimal withdrawal performance and shear slip resistance. In particular, a nail has a head, a tip, and an elongate shank with a first deformation and a second deformation. The first deformation is positioned closer to the tip. When the nail fastens a first substrate to a second substrate, the first deformation is positioned completely in the second substrate to provide withdrawal resistance from the second substrate. The second deformation intersects the plane between the first and second substrates to provide resistance to shear slip. Moreover, the second deformation makes contact with the inner surface of the bore created by the first deformation.

A nail, comprising:
- an elongate shank with a longitudinal axis, a first end, and a second end;
- a head positioned at the first end;
- a tip positioned at the second end;
- at least one annular ring formed on the shank and extending radially outward;
- and
- at least one ridge formed on the shank and defining a helix around the longitudinal axis,
- wherein the at least one ridge is positioned axially between the head and the at least one annular ring.
A nail, comprising:
- an elongate shank with a longitudinal axis, a first end, and a second end;
- a head positioned at the first end;
- a tip positioned at the second end;
- at least one annular ring formed on the shank and extending radially outward;
- and
- at least one axially elongate rib formed on the shank and protruding transversely outward,
- wherein the at least one axially elongate rib is positioned axially between the head and the at least one annular ring.
A nail, comprising:
- an elongate shank with a longitudinal axis, a first end, and a second end;
- a head positioned at the first end;
- a tip positioned at the second end;
- at least one ridge formed on the shank and defining a helix around the longitudinal axis;

- a first deformation formed on the shank;
- and
- a second deformation formed on the shank and positioned between the head and the first deformation;
- a first substrate;
- and
- a second substrate,
- wherein the nail fastens the first substrate in abutment with the second substrate, forming a plane between the first substrate and the second substrate,
- the first deformation is positioned in the second substrate and resists axial movement by the nail, and
- the second deformation intersects the plane and resists shear movement by the first substrate relative to the second substrate.
A fastened assembly, comprising:
- a nail with a total axial length, the nail comprising:
- an elongate shank with a longitudinal axis, a first end and a second end;
- a head positioned at the first end;
- a tip positioned at the second end;
- a first deformation formed on the shank;
- and
- a second deformation formed on the shank and positioned between the head and the first deformation;
- a first substrate;
- and
- a second substrate,
- wherein the nail fastens the first substrate in abutment with the second substrate, a plane being formed between the first substrate and the second substrate,
- the first deformation resists axial movement by the nail, the first deformation being positioned in the second substrate and axially spaced from the plane by at least approximately 25% of the total axial length, and
- the second deformation resists shear movement by the first substrate relative to the second substrate, the second deformation being positioned to intersect the plane and extending axially in both directions from the plane by at least approximately 10% of the total axial length.
A nail for joining two substrates, the nail having a total axial length, the nail comprising:
- an elongate shank with a longitudinal axis, a first end and a second end;
- a head positioned at the first end;
- a tip positioned at the second end;
