A device for measuring the wrenching height of hexagonal head fasteners has a height indicator having an indicator shaft which extends therefrom. The height indicator is actuable by reciprocal movement. A gaging element housing is coupled to the height indicator and has an interior bore with a longitudinal axis with indicator shaft extending into the interior bore. A gaging ring is fixed to gaging element housing and has a central opening of a size selected as a minimum diameter for receiving a hexagonal head of a fastener to be measured. At least three gaging pins are received within pin holes of the gaging ring. Thin gaging pins reciprocate within the pin holes between an inward and outward position. By positioning the gaging ring over a hexagonal head of the fastener being measured, the gaging pins will engage a washer surface so that they are forced inward, actuating the indicator shaft of the height indicator so that the wrenching height of the hexagonal head fastener is measured.
