Abstract
The diameter of a thread is measured by screwing two gauge elements into simultaneous engagement with the thread to be measured, then turning the two gauge elements relative to one another to a setting in which their similar threads bear in opposite axial directions against the thread to be measured and confine that thread in a manner holding it against axial movement relative to the gauge elements, after which the diameter of the measured thread is determined by noting the relative rotary position of the two gauge elements, as indicated by relative positions of coacting markings on those parts.
