Mitutoyo MHM 1-15 Micrometer Head

It’s part of Mitutoyo’s MHM series (“universal” micrometer heads), with a measuring range of 0–15 mm.

It uses carbide-tipped measuring faces, which improves wear resistance.

The standard (analog) version has a 0.01 mm graduation (i.e., each mark on the thimble = 0.01 mm).

The maximum permissible error (i.e., accuracy) is ± 2 µm.

The spindle pitch is 0.5 mm, according to the spec sheet.

The stem diameter is 9.5 mm (plain) for some variants.
