Abstract

Una vite per serraggi di precisione presenta una parte di impegno maschio femmina avente un profilo a stella con lobi radiali (7) aventi fianchi (8) contenuti in piani passanti per l'asse della vite. Le superfici radialmente esterne dei lobi giacciono su una superficie cilindrica o prismatica a generatrici parallele all'asse della vite. La vite è impegnabile da una chiave conica di sezione corrispondente a quella della suddetta parte di impegno. Possibile applicazione come vite anti-furto per ruote di autoveicoli.(Fig. 1)
