M304.054 Micrometer (75–100 mm) — 0.01 mm graduation, ratchet stop

M304.054 is a robust outside micrometer designed for precise dimensional checks in metalworking and inspection benches, featuring an analogue 0.01 mm graduation and a mechanical counter for efficient repeated measurements

• Precision 0.01 mm graduation
• Measuring range 75–100 mm
• Ratchet stop for consistent force
• Complies with DIN 863 standard

Accurate readings for routine quality control

The outside micrometer delivers an analogue 0.01 mm division, providing the standard resolution expected in workshop metrology and enabling clear, verifiable measurements for production control. Built to DIN 863, the instrument meets recognised shop-floor standards and is suitable for serial checking of turned or milled parts. The mechanical counter simplifies repetitive tasks by helping to track incremental adjustments without interrupting the measurement workflow, reducing transcription steps and speeding up inspection cycles.

Repeatability through controlled measuring force

A built-in ratchet stop enforces a consistent contact pressure, which substantially reduces operator-induced variation and improves repeatability between readings. The spindle advances with a 0.5 mm pitch, translating hand motion into fine axial movement that is easy to control; the spindle body has a 6.5 mm diameter for stable guidance. Together with hardened measuring faces, these elements minimise wear and preserve the instrument’s zero and accuracy over extended use, so bench checks stay reliable even after sustained daily operation.

Ergonomics and durability for the workshop

The instrument combines practical ergonomics with durable finishes: a matt chrome-plated thimble resists glare and offers a tactile surface for precise adjustments, while the overall mechanical design avoids electronic failure modes common in harsh environments. As an analogue micrometer with a mechanical counter, it is particularly suited to environments where robustness and serviceability are priorities. Supplied by Metav IndustryLine, the device benefits from a European quality filter and logistics base that support predictable procurement and stocked availability for maintenance and replacement needs.
