ABSTRACT:
An apparatus and method for measuring and recording the torque applied to a bolt. The present invention utilizes a piezoelectric compound disposed between an upper member and a lower member. When the bolt is tightened, the piezoelectric compound is physically distorted and a net electrical potential is created across the piezoelectric compound. A processor in the bolt measures the electrical potential and calculates the torque based on the potential. The bolt then transmits a data packet comprising the torque value and bolt information to a wrench, which later transmits the data packet to a computer and a database. Alternatively, the bolt can be configured with a transmitter so that the data packet can be transmitted directly from the bolt to the computer and database. The bolt can also be configured with energizing circuitry that acts as a power source for the bolt.
