Abstract (en)

[origin: CA2799768A1] The invention relates to an electrically conducting screw connection between two parts (10, 12) which are fastened to each other by a screw (16) having a screw head (18) and a shaft (22) and by a nut (28), wherein the screw (16) extends through a hole (14) in one of the parts (10), wherein the electrical contact between the other part (12) and the screw (16) is established by teeth (27) on the workpiece-side surface of the screw head (18) and/or of the nut (28) or of a washer (30) arranged between the nut (28) and the outer part (12), while the contact between the screw (16) and the one part (10) is established by elevations (26) on the shaft (22) of the screw (16), the outer diameter of the elevations being slightly greater than the inner diameter of the hole (14) and the elevations being arranged between the external thread (24) and the screw head (18), wherein the elevations (26) have flanks (42, 44) that extend at an angle and that meet each other at an angle of approximately 60° and that are connected to each other by circular arc sections (46, 48).
