Mitutoyo 110-111 Micrometer Head, Differential Screw Translator (Extra-Fine Feeding) Type, 0-0.05" Range, 0.00005" Graduation, +/-0.0002" and +/-0.00006" Accuracy, Clamp Nut

The Mitutoyo 110 series micrometer head has a differential screw movement and a vernier scale in inch units for taking precise, high-resolution measurements with a spindle travel of 0.01” per revolution for extra-fine adjustment. It has a clamp-nut stem for quick mounting of the micrometer in a fixture. The vernier scale is graduated to 0.0005”, 0.0002”, or 0.000005” depending on the model, and has a satin chrome rust- and glare-resistant finish. The spherical measuring face is lapped to help provide accuracy.

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. Micrometer heads are for mounting in fixtures, where they are typically used for measurement, or as stops or feeds.

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.
