Mitutoyo 103-146-10 Mechanical Outside Micrometer

Product Description

The MITUTOYO 103-146-10 is a mechanical outside micrometer designed for precise linear measurement in workshop and light industrial settings. It delivers a graduation of 0.01 inches and an accuracy of 0.0001 inches, making it well-suited for dimensional inspection work where tight tolerances matter. The measuring faces are solid carbide, providing wear resistance under repeated use. A ratchet stop thimble applies consistent measuring pressure, reducing operator-to-operator variation. The lightweight workshop design keeps fatigue low during extended measurement sessions. A standard bar is included for calibration verification. Machinists, tool-and-die workers, quality control technicians, and precision tradespeople are the primary users of this instrument.

This outside micrometer is used for measuring the external dimensions of round stock, shafting, fasteners, machined parts, and similar workpieces. Its solid carbide anvil and spindle face make it appropriate for repetitive production measurement as well as bench-level inspection tasks. The ratchet stop thimble is particularly useful in high-volume inspection environments where consistent contact pressure must be maintained across multiple readings. It is equally at home in a manufacturing shop or a mechanical contractor's precision measurement kit.

Key Features

• Graduation of 0.01 inches for fine linear measurement resolution
• Accuracy of 0.0001 inches for high-precision dimensional inspection
• Solid carbide anvil and measuring face for extended wear life
• Ratchet stop thimble ensures consistent, repeatable contact pressure
• Lightweight workshop design reduces operator fatigue during extended use
• Includes standard bar for on-site calibration verification

Compatibility

Designed as an OEM-style outside micrometer for general workshop and precision measurement applications where 0.01-inch graduation instruments are specified.

Installation Notes

Outside micrometers require no installation but should be handled and stored carefully to protect measuring faces from impact and contamination. Before use, verify calibration against the included standard bar and clean all measuring surfaces with a lint-free cloth. Never force the thimble against a workpiece — allow the ratchet stop to control contact pressure. Store the micrometer with a slight gap between anvil and spindle to prevent thermal stress on the frame.
