True Precision

The Multi-Ball micrometer patented design utilizes 3 balls as contact elements. By turning the friction thimble the balls are rolled into contact with the work piece. Since they are free floating they will never evolve flats or wear unevenly. Unlike other kinds of gages the Multi-Ball micrometer contact elements can be positioned anywhere along the thread. The most common locations are at 180 and 120. Calibration is performed in a matter of seconds by adjusting the calibration sleeve on the micrometer to correspond with the size of a solid setting-ring.
