Screw sockets. - In sheet-metal lock cases and door bolt plates the recesses for the heads of the attachment screws are formed by pressing up the metal around each screw hole 3 so as to form an annular projection 4. This projection may be formed in one or more operations ; preferably the metal is first pressed outwardly and the central portion then pressed inwardly.
