Abstract: A measuring device including a gage having a dial, a pointer associated with the dial, and an actuator stem operatively coupled to the pointer; and a coupling mechanism having a connector portion detachably secured to the actuator stem; and a receiver portion defining a recess having first and second longitudinally extending, transversely spaced apart and parallel support surfaces. Also included is a probe pin disposed in the recess, the probe pin being longitudinally aligned with and supported by the first and second support surfaces; and a retainer mechanism exerting on the probe pin a force directed toward the first and second support surfaces. The coupling mechanism permits use of the gage with diametric gage pins selected from commercially available sets of such pins.
