Micrometers are precision measuring instruments used to obtain extremely accurate measurements of small distances, typically thicknesses or diameters. They consist of a calibrated screw and a spindle that moves to measure the object between the spindle and anvil. Micrometers come in different types, such as outside, inside, and depth micrometers, each designed for specific measurements. The readings are usually displayed in millimeters or inches, making them essential tools in machining, engineering, and quality control processes.
