    Micrometers

    Micrometers are measuring instruments often used in mechanical engineering, machining, and technical professions due to their accuracy in measuring extremely small components and fine materials. They are also known as ‘micrometer screw gauges’ due to the calibrated screw that is used to obtain the precise measurements.    At RS we stock a range of Micrometers including calibrated Micrometers, from leading brands like Mitutoyo and Starrett, both brands often chosen for their durability and ease of use. We also have a wide selection of RS PRO Micrometers available for fast delivery with the added benefit of a 3-year warranty. RS also has technical advisers on hand to provide you information not only on the product, but also on our calibrated services.

    Types of Micrometers

    Micrometers are available in both metric and imperial units, allowing for precise measurements in your preferred system. Learn how to calibrate and use micrometers correctly in our comprehensive micrometers guide.

    • External micrometer: most common type used to measure external dimensions such as the outside diameter of an object.
    • Internal micrometer; used to measure inside dimensions like the inside diameter of a hole or tube. There are two types: calliper-type and tubular and rod.
    • Depth micrometer: these are used to measure the depths of holes, slots and steps. They come with a variety of interchangeable rods of different lengths so that they can be used to measure a range of depths
    • Blade micrometer: designed to measure narrow grooves, slots, keyways, and other hard-to-reach dimensions. They feature thin, blade-like anvil and spindle tips that can fit into tight spaces
