M309.042 micrometre (0–25 mm, 0.01 mm) — Metav IndustryLine

The M309.042 is a workshop micrometre designed for precise external measurements across small components and parts; its combination of a rounded anvil and ratchet stop makes it suitable for assembly and inspection tasks.

• 0.01 mm resolution for fine measurements
• Rounded anvil for reliable contact
• Ratchet stop for consistent measuring force
• Painted frame with matt‑chromed sleeve

Precision that pays off in everyday measuring

This micrometre delivers a readable 0.01 mm resolution and an implied repeatable error of ±0.004 mm, which places it well above basic hobby tools and into the realm of professional workshop metrology. The analogue drum scale is quick to read and, with the integrated ratchet stop, the instrument limits operator‑induced variation by ensuring a consistent measuring force for each contact. For routine quality checks and setup work, this balance of clarity and control shortens cycle times and reduces rework.

Built to withstand the workshop environment

A painted frame provides durable protection against knocks and handling, while the matt‑chromed measuring sleeve resists wear and keeps graduations legible. The combination of a compact form factor and a total weight of 0.4 kg makes the instrument easy to handle during long inspection runs without sacrificing stability. The spindle finish and frame design focus on longevity, so maintenance intervals are extended and downtime is reduced.

Measurement features explained for practical use

The instrument uses a rounded anvil paired with a flat measuring face, a configuration that helps centre cylindrical parts and reduces point loading on small diameters. The spindle has a 0.5 mm pitch, giving tactile, predictable advance with each turn; the spindle diameter of 6.5 mm adds stiffness where it matters most. These characteristics simplify comparison measurements and positioning tasks in metalworking and light engineering.

Suitable applications and handling notes

Engineers and technicians in assembly, small‑series production and inspection will find the instrument suitable for external dimension control of shafts, pins and turned parts. The analogue readout and mechanical ratchet are particularly useful where electronic systems are unnecessary or would complicate setup. Regular cleaning of contact faces and light lubrication of the spindle will preserve accuracy and operational feel.

FAQ

What measuring range does this instrument cover?
The M309.042 micrometre covers a 0–25 mm measuring range, making it ideal for small external measurements in workshop and inspection environments.

How fine are the readings and how accurate is the micrometre?
Readings are at 0.01 mm resolution and the device achieves an accuracy of ±0.004 mm, suitable for routine precision work on turned and machined parts with the Metav IndustryLine quality standard.

Why is the rounded anvil useful?
A rounded anvil helps centre cylindrical parts and reduces local deformation on small diameters, which improves repeatability when using this micrometre for shaft and pin measurements.

Does the instrument include a ratchet stop and why does that matter?
Yes — the ratchet stop ensures a reproducible measuring force on each measurement, which reduces operator‑induced error and supports consistent results with the M309.042 micrometre.

What materials and finishes are used on the micrometre?
The frame is painted for durability and the measuring sleeve is matt‑chromed to protect graduations and reduce wear while maintaining legibility.
