Mitutoyo 103-148-10 Mechanical Outside Micrometer

Product Description

The MITUTOYO 103-148-10 is a mechanical outside micrometer designed for precise linear measurement in workshop and field environments. It features a 0.01-inch graduation and an accuracy of 0.0001 inches (5.00 micrometers), making it suitable for close-tolerance measurement tasks in machining, fabrication, and inspection work. The spindle is 6.35 mm in diameter and does not rotate, which helps protect the workpiece surface during measurement. A ratchet stop thimble provides consistent, repeatable measuring force across uses. The unit ships with a standard bar and weighs 2.9 pounds.

This outside micrometer is built for general workshop use in manufacturing, metalworking, and maintenance environments. The lightweight workshop design makes it practical for bench measurement as well as on-site inspection. It is typically installed or used by machinists, tool-and-die technicians, maintenance mechanics, and quality control professionals who require reliable manual measurement without digital readout. The fixed anvil and solid carbide measuring faces make it well suited for measuring external dimensions of round stock, flat stock, and machined components.

Key Features

• 0.01-inch graduation with 0.0001-inch accuracy (5.00 micrometers)
• Solid carbide anvil and measuring face for durability and wear resistance
• Ratchet stop thimble for consistent, repeatable measuring force
• Non-rotating spindle protects workpiece surface contact
• Lightweight workshop design for bench and field use
• Includes standard bar for verification and calibration reference

Compatibility

Designed as a standard outside micrometer for general workshop and inspection applications where manual mechanical measurement to 0.0001-inch accuracy is required.

Installation Notes

Outside micrometers require no installation but should be zeroed and verified against the included standard bar before use. Keep measuring faces clean and free of debris prior to each measurement. Store in the supplied case or a protected location to prevent damage to the anvil and spindle faces. Calibration and verification should be performed per your shop quality procedures or applicable metrology standards.
