micrometer screw gauge

A micrometer screw gauge is a precision measuring instrument used to accurately measure small distances or thicknesses. It consists of a calibrated screw with a pitch of 0.5 mm or 1 mm. The object to be measured is placed between the anvil and the spindle, and then the thimble is rotated to move the spindle towards the object. The measurement is read from the scale on the sleeve and thimble. The accuracy of a micrometer screw gauge is typically to within 0.01 mm or even 0.001 mm, making it suitable for applications where high precision is required, such as in engineering, manufacturing, and quality control. Due to its small size and precise measurements, the micrometer screw gauge is an essential tool for ensuring the accuracy of components and products.
