223-125 Outside Micrometers

Measure gears so they fit perfectly in your system. The anvil and spindle have flat discs that fit between tight gear teeth, where most micrometers can't reach.

To find your exact measurements, read the scales on the sleeve and thimble. You don't have to replace any batteries, so these micrometers are always ready for the job.

Mitutoyo—The go-to for machinists and engineers. Every part is made within a Mitutoyo automated factory and tested in-house in Japan. The spindle glides as you turn the thimble with a weighty, silky-smooth feel.

With Analog Display—Watch the display update as the spindle moves for easy-to-read, trustworthy measurements.

Calibration Certificate—Choose these micrometers when precision measurements are required for quality control or by regulation. The certificate is traceable to NIST, so you can be confident your measurements are correct and consistent.

Ratchet-Stop Thimble—Best for consistent, repeatable measurements. The spindle stops extending the moment it reaches your part, so it won’t overtighten. Hear and feel a satisfying click that confirms you’ve applied the right amount of pressure.
