Micrometers �A micrometer is a widely used device in mechanical engineering for precisely measuring thickness of blocks, outer and inner diameters of shafts and depths of slots. �Micrometers have several advantages over other types of measuring instruments like the vernier caliper they are easy to use and their readouts are consistent. 3/1/2021 Exp. 3: Micrometers &Feeler, Pitch, Radius and Dial gauges 3
