Abstract
A fastener includes an elongated body having a first end and a second end, a helical thread having a crest, a root, and flank portions formed on at least a portion of the elongated body, and at least one protrusion extending from the crest and flank portion. The at least one protrusion is an axially extending V-shape of the crest, flank portions, and root of the helical thread with a peak of the at least one protrusion having a ridge that extends radially outward from the root of the thread.
Claims14
A fastener comprising:
- an elongated body having a first end and a second end;
- a helical thread formed on at least a portion of the elongated body, the thread comprising a crest, a root, and flank portions;
- at least one protrusion extending from the crest and flank portions, the at least one protrusion having a first side and a second side,
- wherein the helical thread defines an interruption,
- the interruption having a first side and an opposing second side, the first side of the at least one protrusion defusing the first side of the interruption,
- a portion of the helical thread positioned opposite the at least one protrusion defining the second side of the interruption, the first side of the at least one protrusion defining a plane that is about parallel with a longitudinal axis of the elongated body;
- and
- a downward protrusion extending from the crest and flank portions toward the second end of the elongated body, the downward protrusion is an axially extending V-shape of the crest, flank portions, and root of the helical thread with a peak that extends radially outward from the root of the thread.

A fastener comprising:
- an elongated body having a first end and a second end;
- a helical thread formed on at least a portion of the elongated body, the thread comprising a crest, a root, and flank portions;
- at least one upward protrusion extending from the crest and flank portions, and
- a downward protrusion extending from the crest and flank portions of the helical thread toward the second end of the elongated body,
- wherein,
- the at least one upward protrusion defines an interruption in the helical thread, the at least one upward protrusion has a first and second side located opposite one another and adjacent to the interruption,
- the interruption has a first side and an opposing second side,
- the first side of the protrusion extends towards the first end of the elongated body,
- a portion of the helical thread positioned adjacent to the second side of the interruption is positioned opposite a bottom end of the first side of the protrusion, and
- the downward protrusion is an axially extending V-shape of the crest, flank portions, and root of the helical thread with a peak that extends radially outward from the root of the thread.
