    摘要: An anchor bolt having a substantially cylindrical stem (2), and at least one thread provided on the stem (2) and extending from a free front end of the stem at least over a portion of a longitudinal extent of the stem (2), the thread (6) having a plurality of thread turns (6) having, at least over one/third of the stem (2), a width (b1, b2) which decreases, with an increase of a distance of a respective thread turn (6) from the free front end of the stem (2), so that a distance (x1, x2, x3) between trailing and leading flanks (8, 7) of two following one another thread turns (6) of the thread increases backwards.
