Abstract (en)
[origin: WO2016093759A1] The present invention relates to a concrete screw (1) comprising; a head portion (3) comprising a head member (5) adapted to fit to a mounting tool, a first shaft (7), substantially uniformly rod shaped having an essentially uniform first diameter (d1), and a second shaft (9), substantially uniformly rod shaped having an essentially uniform second diameter (d2). The concrete screw (1) further comprises a front section(11) comprising an outer surface (13) and a front end (15), and threads (17) having an essentially uniform third outer diameter (d3), wherein the threads (17) are arranged on the second shaft (9) and the front section (11). The outer surface (13) of the front section (11) has a fourth diameter (d4), smaller than the first, second and third diameters (d1, d2, d3), and wherein the threads (17) keep their third outer diameter (d3) on the smaller fourth diameter (d4) of the front section (11).
