Abstract
A feature of a countersink in a hole, such as the diameter, is measured by a gauge having a self centering, spherically shaped probe which shifts laterally upon engagement with the countersink side walls to as to align itself with the central axis of the hole. The gauge includes an outer tube gripped by a user during the measurement, and an axially displaceable shaft within the tube that drives an indicator dial. The shaft is coupled with the probe by a flexible connector which transmits axial displacement of the probe to the shaft but allows slight lateral movement of the probe relative to the shaft, permitting the probe to become centered within the countersink.
