Abstract A ring-shaped washer (10) especially for wood screws (28) has an exter-nal circumferential edge area, which is directed downwards and cuts the wood (26) when the washer is being driven into it. At the same time the wood below the washer is compressed. This primarily serves to avoid a splitting up of the wood when screwing in the wood screw (28) and at the same time to increase the strength of the screwed connection.
