Micrometers are precision measuring instruments used to accurately measure small dimensions such as thickness, diameter, and length with very high accuracy. They are commonly used for fine measurements where tight tolerances are required in mechanical and industrial applications. Micrometers operate using a calibrated screw mechanism that converts small rotational movements into precise linear measurements. Available in various types such as outside micrometers, inside micrometers, depth micrometers, and digital micrometers, they come with different measurement ranges and resolution levels. Micrometers are widely used in manufacturing, machining, quality control, laboratories, and educational institutions, contributing to precise measurement, reliable inspection, and improved product quality.
