<P>PROBLEM TO BE SOLVED: To provide a nut which is attached to a coated member and which can secure electric conduction between the coated member and itself without producing coating film debris. <P>SOLUTION: The nut to be mounted on a screw inserted through a mounting hole or a mounting groove of the coated member A has a protruded portion 2a on at least one face where a tap hole 1 opens. In a state where the face including the protruded portion 2a is opposed to the member A, the screw is fastened into the tap hole 1, whereby the front end of the protruded portion 2a breaks through the coating film on the member A to establish an electrically conductive condition between the member A and itself. The front end of the protruded portion 2a is just pressed against the member A when breaking through the coating film, therefore producing almost no coating film debris. <P>COPYRIGHT: (C)2012,JPO&INPIT |
