    For Use On

    Digital Outside Micrometers for Small Holes, Grooves, and Keyways

    Image of Product. Front orientation. Outside Micrometers. Digital Outside Micrometers for Small Holes, Grooves, and Keyways.
    Find the outer dimensions of grooves in pins and other small parts, then quickly view your readings. The anvil and spindle are as thin as a pencil point to slip into narrow spaces where standard ones won't fit.
    With an LCD display, these micrometers give instant measurements—no need to read scales. Swap between inch and metric or set the position to zero, all with the press of a button. You don't need to reset the zero point since they retain their position when turned off, also known as absolute (ABS) positioning.
    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 SPC Data Output—Send measurements to a computer or data processor to store, analyze, and manage data. You'll need a data cable or SPC wireless transmitter and receiver.
    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.

    Outside Micrometers for Screw Threads

    Image of Product. Front orientation. Outside Micrometers. Outside Micrometers for Screw Threads.
    Make sure screws fit precisely in threaded holes. The anvil and spindle each have a 60° point to fit between standard thread grooves.
    To find your exact measurements, read the scales on the sleeve and thimble. These micrometers are free of electronic components that could break if dropped or short-circuit if wet. You don't have to replace any batteries, so they're always ready for the job.
    Starrett—Precision machined and tested in the U.S. These Starrett micrometers come packaged in their iconic red case, so you'll be able to spot them on the busiest of bench tops.
    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.
