Metav IndustryLine M304.418 Outside Micrometer — 250–275 mm, 0.01 mm resolution with ratchet stop

The Metav IndustryLine M304.418 is an outside micrometer designed for precise diameter and thickness checks on larger workpieces in machine shops and inspection benches.

• Ratchet stop for repeatable torque
• 0.01 mm graduation for fine readings
• Range 250–275 mm for large components
• Powder-coated frame, matt chrome drum

Reliable measurements that speed up quality control

The ratchet-equipped analogue micrometer delivers consistent measurement force, reducing variability between operators and speeding up routine checks. With a 0.01 mm graduation the device provides fine resolution suitable for workshop-level inspection and process control; the spindle pitch of 0.5 mm ensures predictable movement per revolution, so readings are straightforward to interpret. Conformity with DIN 863 gives assurance that the gauge meets common metrological expectations in metalworking environments, supporting repeatable part acceptance and traceable measurement routines.

Built for the workshop: durable finish and intuitive handling

A powder-coated frame in blue resists chips and corrosion typical in production settings, while the matt-chrome measuring drum reduces glare for easier reading. The construction maintains a steady feel during measurement cycles; the instrument’s overall weight of 2.1 kg contributes to stability when checking larger components across the 250–275 mm span. The presence of fixed measuring faces simplifies external measurements of shafts, flanges or castings, making the micrometer a dependable bench tool for maintenance, jigs and fixture verification.

Simple operation and long service life with low upkeep

The integrated ratchet stop prevents over-tightening and helps achieve repeatable results during batch inspections, which reduces scrap and rework. The analogue scale and mechanically precise spindle (measuring spindle diameter 6.5 mm) are easy to maintain: keep contact surfaces clean and apply light oil to the spindle threads at regular intervals to preserve smooth motion. For workshops seeking a practical balance of precision and robustness, this micrometer supports efficient throughput without the complexity of electronic devices, while offering a tactile, dependable measuring experience.
