Abstract
A method and device for measuring screw threads on tubes connecting sleeves or the like, by means of a measuring pin which is moved to measured surfaces in two mutually independent measuring directions offset by 90.degree. from each other. The two measuring directions are associated with a force direction effective as a resultant. The measuring pin further has an advance deflection in each of the two measuring directions which are annulled at the point contact of the measuring pin with the measured surfaces.
