Abstract

Flat gasket with a gasket plate which has at least one screw hole for the passage of the threaded shaft of a screw and is formed in the region of this screw hole by a sheet-metal layer, the sheet-metal thickness of which would make an engagement of the sheet-metal layer in a thread of the threaded shaft possible, wherein for the secure centering of the threaded shaft in the screw hole the sheet-metal layer has in its edge region bordering on the screw hole at least one centering element which is formed by the sheet-metal layer and bent out of its plane and prevents any engagement of the sheet-metal layer in a thread, the centering element being designed such that it can be bent back at least approximately into the plane of the sheet-metal layer during the tightening of the screw.
