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.

Starrett—Precision machined and tested in the U.S.

McMaster-Carr Approved—The performance of brand-name micrometers without the cost.

With Heat-Insulated Frame—Prevent the micrometer from expanding due to heat from your hand, which can distort your measurements.

Decimal Equivalent Table—Quickly convert fractions to decimals using the table stamped on the frame.

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.

Friction Thimble—Control how tightly the spindle closes on your part without the risk of damaging it. You can keep extending the spindle in small increments once it reaches your workpiece but not enough to overtighten. The thimble will start to resist turning to let you know you’ve applied the right amount of pressure.

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.
