Mitutoyo 103-147-10 Mechanical Outside Micrometer

Product Description

The MITUTOYO 103-147-10 is a mechanical outside micrometer designed for precise dimensional measurement in machine shops, manufacturing facilities, and maintenance environments. It delivers an accuracy of 0.0001 inches (5.00 micrometers) with a graduation of 0.01 inches, making it suitable for applications that demand repeatable, high-resolution linear measurement. The thimble uses a ratchet stop mechanism to apply consistent measuring force, reducing operator-induced variation. The measuring faces and anvil are solid carbide for wear resistance. A satin chrome coating provides corrosion resistance and reduces glare in workshop lighting. A standard bar is included for calibration verification.

This micrometer is used in precision measurement tasks across metalworking, tooling, and quality inspection. Its lightweight workshop design makes it practical for bench use and line inspection. The ratchet stop thimble is particularly well suited for technicians who perform repetitive measurements and need consistent spindle pressure without over-tightening. The solid carbide measuring faces hold up under regular contact with hardened steel, cast iron, and other abrasive workpiece materials.

Key Features

• Accuracy of 0.0001 inches (5.00 micrometers) for high-resolution dimensional checks
• Graduation of 0.01 inches for clear, readable measurement increments
• Ratchet stop thimble ensures consistent measuring force across multiple readings
• Solid carbide anvil and measuring faces provide extended wear life
• Satin chrome finish resists corrosion and minimizes glare
• Includes standard bar for calibration verification

Compatibility

Designed as an OEM-style mechanical outside micrometer suitable for general-purpose outside diameter and thickness measurement in workshop and inspection environments.

Installation Notes

Outside micrometers are used by machinists, quality control technicians, and metrologists and do not require permanent installation. Before use, verify calibration with the included standard bar and zero the instrument per the manufacturer procedure. Keep the measuring faces clean and free of debris before contact with any workpiece. Store in the provided case and away from temperature extremes to maintain calibration stability.
