Metav IndustryLine M304.249 — Outside micrometre, 25–50 mm, large matt‑chrome drum & friction ratchet

The Metav IndustryLine M304.249 outside micrometre is a mechanical 25–50 mm instrument designed for routine workshop and quality checks where repeatable measuring force and durable components are required.

Large matt‑chrome measuring drum
Friction ratchet for repeatable force
Hardened measuring faces included
Complies with DIN 863 standard

Consistent results thanks to repeatable measuring force

The central advantage of this mechanical micrometre is its friction ratchet, which limits user‑applied force and thus improves repeatability across multiple measurements. With a standard reading of 0.01 mm, the instrument delivers the resolution expected in workshop metrology while complying with DIN 863, so results are traceable to common industrial expectations. The 25–50 mm range covers most small‑component measurements, offering a balance between reach and rigidity that supports reliable thickness and diameter checks in production and inspection routines.

Durable build and glare‑free handling for daily use

Designed for everyday handling, the micrometre features a matt‑chrome drum that reduces surface reflections and eases visual reading in brightly lit environments. The measuring faces are hardened, extending service life and maintaining dimensional integrity under frequent contact with metal parts. At approximately 0.7 kg, the instrument feels substantial yet manageable on the workbench; it is supplied in a protective case (plastic or wooden, depending on transport needs) to prevent damage during storage and transit. Together, these design choices lower life‑cycle costs and reduce the need for premature replacement.

Clear mechanical specification for fast integration into workflows

The instrument is a mechanical (analog) micrometre with a spindle pitch of 1 mm and a precision spindle diameter that supports stable operation. Its simple, tactile operation makes it suitable for standard workshop quality control and toolroom tasks where digital interfaces are not required. The combination of a robust drive mechanism and a friction control ensures that measurements are repeatable and reproducible, which helps maintain consistent process control across shifts. The pragmatic design supports quick familiarisation for technicians and fits seamlessly into existing inspection routines.

FAQ

What measuring range does the micrometre cover?
The instrument covers a measuring range of 25–50 mm, making it suitable for small to mid‑sized components typically encountered in workshop and inspection tasks.

What accuracy and resolution can be expected from this mechanical micrometre?
This mechanical micrometre offers a resolution of 0.01 mm and is manufactured to meet DIN 863, ensuring performance appropriate for routine quality control and workshop use.

How does the friction ratchet help with measurements?
The friction ratchet on the micrometre limits the applied spindle force, helping to achieve consistent contact pressure across measurements and therefore improving repeatability of results.

Are the measuring faces durable enough for metalworking use?
Yes, the measuring faces are hardened, which increases wear resistance when measuring metallic components and prolongs the instrument’s service life.

Is the micrometre supplied ready for use and how is it protected during transport?
The micrometre is supplied in a protective case (plastic or wooden, depending on transport requirements) to avoid damage during transit and storage.
