A gauge to evaluate the flatness, planar disposition, and location of the sealing surface of a rotary shouldered threaded connection, the gauge being adjustable and convertible to gauge either pin or box ends of different size connections, with multiple contact shoes engaging the connection threads to hold the gauge fixed relative to the thread pitch diameter and a device to measure distances from the pitch diameter to the shoulder face. In the method, the gauge is moved around the connection to obtain measurements from different circumferential locations to evaluate shoulder flatness and axial location and to examine the angular disposition of the plane of the shoulder face relative to the thread axis.
