M303.161 built-in micrometer — 0–25 mm, large 29 mm drum (Metav IndustryLine)

The M303.161 is a built‑in micrometer designed for precise 0–25 mm measurements in workshop and production environments.

• Large 29 mm drum for clear reading
• Carbide spindle for long wear resistance
• 0–25 mm range with 0.01 mm resolution

Consistent metrology for small, critical parts

This built‑in measuring screw delivers repeatable accuracy through a combination of a calibrated 1 mm spindle pitch and a finely divided scale. The 0.01 mm reading is achieved by the 100 division drum on a 1 mm pitch, which means every full spindle revolution corresponds to 1 mm axial travel and each drum graduation to 0.01 mm. The integrated ratchet mechanism controls measuring force to reduce operator‑induced variation, improving reproducibility for small components and quality‑control tasks.

Built to stay precise under shop conditions

Designed for longevity, the instrument features a carbide spindle and plan‑parallel measuring faces, reducing wear where it matters most. The large 29 mm drum improves legibility and speeds up repetitive inspection cycles, while the robust construction and an 8 mm spindle diameter contribute to mechanical stability during frequent use. Compliance with DIN 863 provides a clear reference for manufacturing tolerances and acceptance criteria in production environments.

Easy integration and application‑specific benefits

Classified in the micro category for its 0–25 mm range, this device is ideal for fine mechanical work such as small assemblies, precision fixtures or watchmaker tasks where compact size and high resolution are required. The 1 mm pitch and 100 divisions simplify interpretation of readings and make training straightforward for operators. As a built‑in variant, the unit suits panel or fixture integration where a permanent or semi‑permanent measuring point is needed, helping to streamline in‑line checks and reduce handling time.

FAQ

What measuring range does this instrument cover?

The M303.161 built‑in micrometer covers a 0–25 mm range, making it suitable for micro‑range inspections and fine mechanical components.

How fine is the graduation and how is it achieved?

The instrument provides a 0.01 mm reading via a 1 mm spindle pitch combined with 100 divisions on the large drum, so each drum graduation equals 0.01 mm.

Is the spindle durable for frequent shop use?

Yes. The carbide spindle fitted to the M303.161 improves wear resistance and maintains accuracy over extended use in production environments.

Can the micrometer be mounted in a fixture or panel?

As a built‑in version, the M303.161 is intended for integration into fixtures or panels where a permanent measuring point is required, supporting inline checks and repeatable placement.

Which standard does this measuring instrument comply with?

The device is manufactured in accordance with DIN 863, providing a recognised baseline for mechanical micrometer dimensions and tolerances.
