Beschreibung
Zusammenfassung:	A fastener is provided including an elongated body having a first end (1) and a second end (12), and a helical thread (20) formed on at least a portion of the elongated body where the thread has a crest (22), a root (25), and flank portions (28). The helical thread has at least one protrusion (50) extending from the crest and flank portions toward the first end of the elongated body, and each protrusion has a peak (52) that extends to the root of the thread. La présente invention concerne un élément de fixation qui comprend un corps oblong ayant une première extrémité (1) et une seconde extrémité (12), et un filet hélicoïdal (20) formé sur au moins une partie du corps oblong où le filet comporte une crête (22), un fond (25) et des parties flancs (28). Le filet hélicoïdal comporte au moins une protubérance (50) qui s'étend à partir de la crête et des parties flancs en direction de la première extrémité du corps oblong, chaque protubérance possédant une pointe (52) qui s'étend jusqu'au fond du filet.
