ABSTRACT:
A micrometer screw gauge comprises a divided measuring spindle. The gauge's front part representing the measuring screw is secured in a torque-proof manner in a guide element. The rear section configured as a threaded spindle has the same diameter. In so doing, it is coupled in an axially rigid but rotatable manner to the measuring screw. This measuring spindle may replace a conventional, rigid, continuous measuring spindle of a micrometer screw gauge and, in so doing, results, without substantial design change, in a micrometer screw gauge comprising a non-rotatable measuring spindle.
