A method of inspecting metallic container components (10) provides indexing a container component (10) produced from a metallic material into axial alignment with a probe (110). The probe (110) has a coil (176) produced from an electrical conductor. An alternating current (183) is applied to the coil (176) wherein a first magnetic field (184) is generated. An eddy current (188) develops in the container component (10) in response to the first magnetic field (184). A second magnetic field (192) is generated in response to the eddy current (188). Changes in an impedance amplitude and phase angle in the coil (176) are measured. A determination of the fitness for use of the container component (10) is made based on the measured changes in the impedance amplitude and phase angle in the coil (176).
