摘要 The invention concerns a hole drawing fastener for placement in holes and other recesses of primarily circular shape in plates and other sheetlike material for transmission of forces to the material in the region around the hole, especially basically in its plane and during straightening work on vehicle bodies, especially when fastening spring struts to them, which hole drawing fastener contains a hold-together element 1 which can be inserted through the hole, preferably a bolt, which is provided at one side of the hole with an element 2 for connection to a force generating arrangement and which furthermore carries a hold-up plate 3; 3a. The purpose of the invention is to create a more universally applicable fastener of this kind. This is achieved primarily in that the hold-up plate 3; 3a has a projecting axial flange 4 at one side of it, which is designed to bear against the material 8 outside the edge of the hole with its free end edge and to accommodate inside itself the narrow end of a conical clamping element 5 inserted in the hole and arranged on the hold-together element at the opposite side of the hole. <IMAGE>
