These mechanical calliper micrometres provide exact measurements on recessed features that ordinary micrometres can't match. To obtain exact measurements on recessed features, These type of micrometre has hardened steel jaws with carbide measuring surfaces and a hardened steel spindle. The ratchet stop mechanism on the micrometre ensures a constant measuring force on the spindle, ensuring accurate and repeatable measurements. When measuring large dimensions, the combination of the ratchet thimble and speeder allows for quick spindle feed for one-handed measurements.
