Abstract
Gasket with at least one sheet-metal layer which has at least one screw hole for the passage of the threaded shaft of a screw, wherein for a secure holding against loss of the screw in the screw hole the sheet-metal layer is designed such that several holding tongues integral with the sheet-metal layer project from the edge of the screw hole, define a circular core hole, the diameter of which corresponds to the core diameter of the screw thread, and are designed for engagement in the screw thread, and that at least some of the holding tongues are bent out of the plane of the sheet-metal layer in such a manner that the edge regions of the holding tongues facing the center of the hole are arranged so as to be offset relative to one another in axial direction of the screw hole in accordance with the pitch of the screw thread.
