Abstract
Threaded mechanical fastening systems and methods are provided that allow the simple deflection of a washer to indicate that a desired minimum torque has been reached or that a desired maximum torque has been exceeded. The method includes providing a threaded connection having a washer, installing the threaded connection so that the washer is supported as a simple beam over a gap, and using an amount of deflection of the washer as a result of torque applied by the threaded connection as an indicator. The torque indicating threaded mechanical fastening system includes a threaded connection and a washer supported as a simple beam over a gap so that the threaded connection, when tightened to a predetermined torque, deflects, in bending, the washer into the gap.
