Abstract: A threaded fastener includes an elongated body having a first end and a second end, a first portion comprising a first helical thread, with the first helical thread including a crest, a root, and flank portions, and a second, tapered portion including a second helical thread. The second helical thread includes a crest, a root, a leading flank portion, and trailing flank portion, with the leading flank portion positioned closer to the second end of the elongated body than the trailing flank portion. A thread angle of the second helical thread is larger than a thread angle of the first helical thread, and the root of the second helical thread includes a root apex formed by the intersection of the trailing flank portion and the leading flank portion.

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.

Abstract: A fastener is provided including an elongated body having a first end and a second end, and a helical thread formed on at least a portion of the elongated body where the thread has a crest, a root, and flank portions. The helical thread has at least one protrusion extending from the crest and flank portions toward the first end of the elongated body, and each protrusion has a peak that extends to the root of the thread.
