Mitutoyo 103-140-10 Outside Micrometer 0.01 in Graduation

Product Description

The MITUTOYO 103-140-10 is a mechanical outside micrometer designed for precise linear measurement in workshop and field settings. It features a 0.01 inch graduation and an accuracy of 0.0001 inches, making it suitable for close-tolerance inspection work. The measuring faces and anvil are solid carbide, providing long-term wear resistance during repetitive use. A ratchet stop thimble delivers consistent measuring force, reducing variation between readings. This micrometer ships with a standard calibration bar and carries a satin chrome finish for corrosion resistance. It is installed and used by machinists, tool-and-die techs, HVAC equipment fabricators, pipefitters, and inspection personnel requiring reliable dimensional verification.

The 103-140-10 is suited for dimensional inspection of round stock, tubing, fittings, and machined components in both residential and commercial trade environments. The lightweight workshop design makes it practical for bench use or carry-to-job applications. The solid carbide measuring faces hold calibration longer than steel-faced instruments under continuous production or service conditions. No digital counter or rotating spindle is present, keeping the instrument mechanically simple and straightforward to maintain.

Key Features

• 0.01 inch graduation with 0.0001 inch accuracy for close-tolerance measurement
• Solid carbide anvil and measuring face for extended wear life
• Ratchet stop thimble provides repeatable, consistent measuring force
• Satin chrome finish resists corrosion in workshop environments
• Lightweight workshop design for bench or field use
• Includes standard calibration bar for field verification

Compatibility

Designed as a standard mechanical outside micrometer for general-purpose dimensional measurement of external features on round and flat workpieces.

Installation Notes

This instrument requires no installation in the traditional sense, but should be calibrated against the included standard bar before first use and periodically during service. Store the micrometer with a slight gap between the anvil and spindle to prevent thermal expansion damage. Clean measuring faces with a lint-free cloth before and after use. Calibration and adjustment should be performed by a qualified metrologist or in accordance with your facility quality procedures.
