The present invention relates to a protrusion sensor that determines the acceptability of a rivet within a component. The sensor includes a baseline detector which remains stationary, a movable detector which moves with a bucking bar module and produces a first signal proportionate to a distance between the baseline detector and the movable detector, and a CPU electronically connected to the movable detector and receiving the first signal. The CPU determines whether the rivet is acceptable by inputting a first distance when the bucking bar module is clamping an inside surface of the component, inputting a second distance when the bucking bar module is seated against a shank of the rivet, subtracting the second distance from the first distance to determine a length of the shank protruding from the inside surface of the component, and comparing the length of the shank against an internal table of rivet lengths to determine whether the proper rivet was loaded into the component or whether the rivet is within an acceptable tolerance.
