Micrometer YATO YT-72303 75–100 mm measuring range, mechanical outside micrometer

The YATO YT-72303 75–100 mm mechanical outside micrometer is a precision hand tool designed for accurate measurement of external diameters and thicknesses within the 75–100 mm range. Constructed for workshop and inspection environments, this micrometer provides clear mechanical readings and stable spindle movement for consistent dimensional checks. Its compact frame and robust build make it suitable for repeated use in metalworking, engineering and maintenance operations where rigid, repeatable measurements are required.

Advantages

This mechanical outside micrometer delivers reliable manual measurement without dependence on batteries or electronics. The hardened measuring faces ensure wear resistance and long-term accuracy, while the calibrated thimble provides readable graduations for direct reading of measurement values. A sturdy frame minimises deformation under normal use, and the friction thimble or ratchet stop helps achieve consistent contact pressure between the anvil and spindle.

Suitable for

• Measuring external diameters of shafts, rods and pipes within 75–100 mm
• Thickness checks of flat parts and plates
• Dimensional inspection in metal workshops and production lines
• Maintenance and repair tasks requiring precise manual measurement

Key specifications

• Measuring range: 75–100 mm
• Type: mechanical outside micrometer
• Measuring faces: hardened for wear resistance
• Reading: calibrated thimble with mechanical graduation
• Frame: compact and rigid design for stability
• Contact control: friction thimble or ratchet stop for consistent pressure

How to use

Place the micrometer so the anvil and spindle surround the workpiece at the point to be measured. Advance the spindle using the thimble until the measuring faces contact the part, then apply the friction thimble or ratchet stop to obtain uniform contact pressure. Read the value directly from the calibrated thimble and sleeve graduations. If greater accuracy is required, take multiple measurements at different orientations and average the results. Store the micrometer in a protective case when not in use and periodically check calibration against a gauge block.

Usage recommendations

Handle the micrometer with clean hands and avoid exposing it to shocks or heavy vibration. Keep measuring faces free of debris and lubricate the spindle lightly if specified by maintenance guidelines. For traceable results, verify calibration at regular intervals and use the ratchet stop to reduce operator-induced variation.
