The ratchet in the micrometer (screw gauge) is a small mechanism inside the screw nut drum, with the purpose of limiting the measuring force of the spindle screw. It works by a calibrated small drum that limits the friction force applied to the measure work piece and produces a ratchet sound when the thimble is locked.
