293-831-30 Outside Micrometers

The simplest-to-use micrometers. Their LCD display gives instant measurements down to 0.00005”—no need to read scales. Swap between inch and metric or set the position to zero, all with the press of a button.

You can always expect accuracy with our micrometers. The anvil and spindle are precision ground to exact dimensions for reliable readings every time.

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.

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.
