Micrometers

A micrometer, also known as a vernier or screw gauge, is a precise measuring instrument used to determine small distances or thicknesses, typically in the range of 0.001 millimeters or 0.0001 inches. It works by tightening a screw against the object, with a graduated scale to read the measurement accurately. Commonly used in mechanical and manufacturing settings, micrometers are essential for ensuring parts are manufactured within exact specifications, providing highly accurate measurements for engineering and quality control.
