Relates to a method and an apparatus for measuring concentricity of a fastener. Systems and methods for inspecting a fastener mounted at least partially through a hole in a component by measuring the concentricity of the fastener, measuring the levelness of the fastener with a surface, and/or detecting foreign debris in the vicinity of the fastener. The system includes an x-ray imaging system, a first camera device, a second camera device, a first support structure, and at least one processing device. A first camera device generates a first image of the fastener from a first favorable point, and a second camera device generates a second image of the fastener from a second favorable point, such that a 3D image of the fastener can be created from the first image and the second image. The system inspects the fastener based on the x-ray image and/or the 3D image to determine concentricity and/or levelness of the fastener. The system may be automated and mounted on a robotic arm to be positioned relative to the fa
