FIELD: measurement equipment.
SUBSTANCE: inserts for a thread micrometre designed for measurement of mean diameter of thread for measurement of linear dimensions even with other measuring means differ by the fact that their surfaces are made in the form of single-stage or two-stage cylinders, the smaller stage of which can be conical, with flat end surfaces perpendicular to their axis and two external and two internal surfaces parallel to axis of cylinders and forming a slot and a projection of similar size A that can be equal to half the standard pitch of thread. Besides, it contacts the cavity and the projection of thread at two points on each side, which allows measuring the thread with various profile angles. In the cross sections perpendicular to axis of cylinders and passing through contact points, diameters of cylinders can be equal to double similar size A. Distance between cross sections is the measured dimension at measurement of threaded or other surfaces.
EFFECT: increasing productivity and improving accuracy of measurements; enlarging the range of measured surfaces and range of measuring means.
