Abstract
In a dimensioning head for a plug gage, a pair of exteriorly projecting balls project through openings on either side of the longitudinal axis of the housing for contacting the inside diameter of the bore hole to be measured. Each of the balls contact a V-shaped groove of a guide surface to the housing to ensure accuracy and repeatability of measurements.
