Abstract

See full text

A sensor unit for inducing and indicating ultra sonic sound waves in at least one threaded fastener by physical contact with an end surface thereof, wherein the sensor unit includes: a support casing, a sensor element with forward contact surface for engaging the fastener end surface and movable relative to the support casing between rest and active positions, and a bias spring between the support casing and the sensor element to urge the sensor element into the rest position as the sensor element is out of contact with the fastener end surface and to bias the contact surface of the sensor element into physical contact with the fastener end surface in the active position. The support casing includes a positioning socket, engaged by the sensor element in the rest position, having a non-cylindrical and non-circular cross sectional inner shape and congruent with an outer shape of the sensor element.
