A transducer assembly for use with a remotely located PC device for determining holding forces of a fastener, the fastener including a head and a shaft extending through first and second layers of material. A tightening nut rotatably secures to an extending end of the shaft. The transducer assembly includes a substantially disk-shaped printed circuit board incorporating at least one circuit configuration for communicating first and second faces of the circuit board. An input line, typically a wire harness, extends from the remote PC and is engageable, at a first location, to the first face of the circuit board. A bolt identification component, incorporating either a resistor or ID chip in a suitable circuit, is engageable at a second location to the first face of the circuit board and is communicable, via the input line, with the PC device to communicate a signal representative of the identity of the bolt to be analyzed. A substantially disk shaped piezo-ceramic is engageable with the second face of the circuit board and is encapsulated within a conforming material which also substantially surrounds the second side of the printed circuit board. The identification device and assembly is bonding, through the application of a suitable adherent or glue, atop the fastener head, and in order to be either reusable or disposable at the election of the use.
