Abstract:
An anchor bolt to be set in a constructional component, comprising a head (3); a substantially cylindrical stem (2) extending from the head and having a front free end (4) remote from the head (3); and at least one thread provided on the stem (2) and extending from the free front end (4) of the stem at least over a portion of a longitudinal extent of the stem (2), the thread (6) having a plurality of thread turn (6) having, at least over a front one/third of the stem (2) measured from the free front end (4), an axial width (b1, b2), which decreases, with an increase of a distance of a respective thread turn (6) from the free front end (4) of the stem (2), so that a distance (x1, x2, x3) between trailing and leading flanks (8, 7) of following one another, in a setting direction of the anchor bolt, thread turns (6) increases in a direction opposite to the setting direction of the anchor bolt, wherein the thread has, over an entire length thereof, a constant medium pitch measured between adjacent reference plans (N) that extend transverse to stem axis (A) and pas through respective transitional points from leading flanks (7) of respective adjacent thread turns to regions of the respective adjacent thread turns spaced radially from the stem (2) by a largest distance.
