The Mitutoyo 103 series outside micrometer has a vernier scale in inch units for taking precise outside diameter (OD) measurements, and a ratchet-stop mechanism for uniform pressure during adjustment. The micrometer’s frame has a baked enamel finish for protection and durability. The vernier scale on the thimble and sleeve is graduated to 0.001”, with a satin chrome rust- and glare-resistant finish. The spindle and anvil have flat measuring faces and are carbide-tipped for wear resistance. A spindle lock helps provide secure locking of the measurement position.
Micrometers are precision measuring instruments that use a calibrated screw to measure small distances. These measurements are translated into large rotations of the screw that are then able to be read from a scale or a dial. Micrometers are typically used in manufacturing, machining, and mechanical engineering. There are three types of micrometer: outside, inside, and depth. Outside micrometers may also be called micrometer calipers, and are used to measure the length, width, or outside diameter of an object. Inside micrometers are typically used to measure interior diameter, as in a hole. Depth micrometers measure the height, or depth, of any shape that has a step, groove, or slot.
Mitutoyo manufactures precision measuring tools, metrology equipment, and systems. The company was founded in Tokyo in 1934 and formed Mitutoyo America Corporation in 1963, which is headquartered in Aurora, IL.

As a precision micrometer that isn't extremely expensive, I couldn't ask for more. Mine is closer to + .0002 inch off but honestly that's perfectly fine since I can add that in my calculations. Excellent product, fairly well built, and does what it's supposed to do.

You get what you pay for. A high quality tool at a very reasonable price! Accurate, easy to use and read. Comes in a quality case. Shy away from the cheaper ones.

I have absolutely no need for a micrometer. I bought it along with a dial caliper and other precision measuring instruments to give my kids a chance to learn more about tools, engineering, and precision measurements. I have been very happy with it. Now all I need is a project that requires one!

Less expensive and better quality (made in Japan) than the Starrett (now made in China)
