The thread engagement verifier system provides for verifying the quality of a threaded connection (12) between upper and lower for tubular member (16, 18). One or more thermal radiation sensors (14) are used in combination with a data acquisition and processing computer (20) and an output device, such as a video display (12). The thermal radiation is generated by sliding friction between the tubular members, and the sensors (14) sense radiation at a plurality of external locations and output heat intensity signals to the computer (20). Torque may also be sensed via a sensor (32) and input to the computer (20).
