Mitutoyo 104-149 Micrometer, 0 - 4" Interchangeable

Mitutoyo Series 104 imperial outside micrometers cover a wide span with one frame. You swap the anvil to move the measuring range, and use the supplied setting standards to set zero. Toolrooms, quality control teams and machine shops that work in inches use them for shafts, tubing thickness, shoulder-edge distance and rivet height. They are analog, with a graduation of .001" on the scale.

An anvil is the fixed measuring face, and a setting standard is a precisely sized bar used to check zero. Graduation is the smallest step marked on the scale. Accuracy is a separate figure: it is the biggest error Mitutoyo allows, so do not read a fine graduation as a promise of that accuracy. Choose 0 - 4" if you only need the smaller sizes and want a lighter instrument, 0 - 6" for general work, or 6 - 12" for larger parts.
