Abstract

A countersink go/no-go gauge is configured to aid a determination of whether a countersink aperture for a rivet is formed to a desired depth. The countersink go/no-go gauge includes a head having a depth defined between a top surface and a bottom surface and a shaft extending from the top surface of the head. The depth of the head is substantially equal to a desired depth of a countersink aperture. In some embodiments the go/no-go gauge includes tolerance features to provide a range for an acceptable countersink depth.
