M304.231 Micrometer (75–100 mm) – Ratchet stop, matt‑chrome thimble by Metav IndustryLine

The M304.231 is a mechanical external micrometer designed for routine workshop inspection and precise component checking across the 75–100 mm measuring range.

• Ratchet stop for reproducible measuring
• Matt‑chrome thimble to reduce glare
• Complies with DIN 863 for workshop accuracy

Consistent mechanics for repeatable results

The instrument relies on a ratchet stop and a robust spindle drive to remove operator variability during closure, which leads to repeatable external measurements. The matt‑chrome thimble reduces surface glare, aiding visual read-off, while the mechanical construction follows DIN 863, a recognised standard for workshop micrometers. These design choices deliver steady performance in daily measurement tasks where reliability matters more than delicate laboratory features.

Clear, industry‑standard resolution and function

With a resolution of 0.01 mm and a spindle pitch of 0.5 mm, the instrument provides the familiar mechanical division system used across workshops: one full thimble rotation equals 0.5 mm axial advance, and the thimble graduations yield hundredth‑millimetre steps. As an analog device, the micrometer is straightforward to read and resilient in harsher environments where electronic displays may be a liability, making it suitable for production floors and inspection benches alike.

Ready for workshop handling and safe transport

The tool is supplied complete with a protective transport case, facilitating secure storage and transport between workstations. The matt‑chrome thimble and the proven spindle geometry support long‑term durability with minimal maintenance, while the compact mechanical design keeps servicing straightforward. Conformity with workshop standards ensures compatibility with existing control routines and traceable measurement practices.

FAQ

What accuracy can be expected from this micrometer?
The M304.231 micrometer provides a standard mechanical resolution of 0.01 mm; as an instrument conforming to DIN 863, it is intended for reliable workshop accuracy in external measurements.

How does the ratchet stop improve measurement quality?
The ratchet stop on the Metav IndustryLine micrometer limits the applied measuring force, preventing excessive pressure and ensuring reproducible contact pressure for consistent readings.

Is the instrument suitable for shop‑floor use?
Yes. The M304.231 is an analog mechanical micrometer with a matt‑chrome thimble and robust spindle design, intended for everyday workshop and inspection tasks rather than delicate laboratory-only applications.

Does the micrometer come with a case?
The micrometer is supplied with a protective case to facilitate safe transport and storage between workstations.

How is the 0.01 mm resolution achieved with a 0.5 mm spindle pitch?
The spindle advances 0.5 mm per full thimble rotation; the thimble is divided so that each graduation corresponds to 0.01 mm, allowing precise mechanical read‑off without electronics.
