Metav IndustryLine Disc-Faced Outside Micrometre M309.253 — 75–100 mm, Ø20 mm disc anvil

The Metav IndustryLine Disc-Faced Outside Micrometre M309.253 is a robust analogue measuring instrument designed for outside measurements in the micro class, handling small components with reliable repeatability.

• 75–100 mm measuring range
• Ø20 mm disc anvil for stable contact
• 0.005 mm specified accuracy
• Ratchet stop for consistent measuring force

Precision for fine mechanical work

This analogue micrometre is specified with a measuring range of 75–100 mm, placing it in the micro class of instruments where compact dimensions meet high demands for precision. The instrument delivers a specified accuracy of 0.005 mm and a reading resolution of 0.01 mm, which together support reliable dimensional control in small parts production and inspection. These figures help to reduce rework and scrap by delivering measurable, repeatable data for routine quality checks.

Stable contact and repeatable force for consistent readings

Equipped with a Ø20 mm disc anvil, the instrument provides a larger contact area than a point anvil, improving stability when measuring rings, small cylinders or slightly irregular surfaces. The integrated ratchet stop prevents over-tightening and standardises the measuring pressure, while the non-rotating spindle avoids rotating the workpiece during measurement. The combination of these features reduces operator influence and produces more consistent results across repeated measurements.

Durable finish and protected transport

The frame is finished with a painted coating and the thimble is matt-chromed, delivering a workshop-hardy surface that resists corrosion and wear from frequent handling. With a stated weight of 1.1 kg, the tool feels balanced in the hand while remaining sturdy during use. The instrument is supplied in a protective transport case, which safeguards the micrometre for storage and shipping and helps maintain calibration and mechanical condition between uses.

Practical applications and workflow benefits

Ideal for precision workshops, toolrooms and quality-control benches, this outside micrometre suits small-series production and routine inspection tasks. The mechanical construction and clear graduations make it straightforward for trained technicians to integrate into existing measurement routines, while the disc anvil and ratchet stop contribute to faster measurement cycles with fewer operator corrections. Where small external diameters and fine tolerances are common, the device supports efficient, traceable measurements that feed into quality documentation.
