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;
- and
- at least one protrusion extending from the crest and flank portions,
- wherein,
- the at least one protrusion defines an interruption in the helical thread and 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 vertically towards the first end of the elongated body, and
- 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.
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 and 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 vertically towards the first end of the elongated body,
- 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.
