摘要： A screw having a shank, wherein the shank has a tip end, a rear end, and a longitudinal axis extending through the tip end and through the rear end, wherein the tip end and the rear end are opposite ends of the shank, and a screw thread, which is connected to the shank, and which winds around the shank, wherein a wedge groove is provided in the shank, which wedge groove winds around the shank and extends alongside at least a section of the screw thread, wherein the wedge groove is delimited by a rearwardly tapered wedge flank for wedging a grout shell surrounding the shank. The screw thread extends further towards the rear end of the shank than does the wedge groove.

摘要： The invention relates to a fastening element, comprising an insertion segment for inserting into a bore, having a self-tapping threaded segment having an external thread for screwing and tapping into the bore on a fastening object, and comprising a mounting segment for arranging outside of the bore, having an interface geometry for applying a torque to the fastening wherein it should be possible to fix a fixing part to the fastening element in a simple manner. This aim is achieved in that the mounting segment is additionally provided with a fixing device for indirectly or directly, in particular interlockingly and/or frictionally, fixing a fixing part on the mounting

摘要： A screw includes a shank having an insertion tip and a head end which has an upper portion with a cutting portion and a lower portion from which a plurality of anti-screw-out teeth protrude. Each anti-screw-out tooth includes a guide face and a stop face intersecting a circumferential surface of the lower portion for development of a recessed channel. A first thread on the shank includes a plurality of asymmetrical thread convolutions each having a first cutting face facing onto the insertion tip and a second cutting face backing onto the insertion tip. The first cutting face and a horizontal axis form an included angle between 25 and 45 degrees. The second cutting face and the horizontal axis form an included angle between 3 and 23 degrees. The screw is in favor of surface flatness of a to-be-connected plank and pull-out as well as anti-screw-out properties of the screw.
