M309.032 – 5‑point outside micrometer, 25–45 mm, 0.01 mm reading (Metav IndustryLine)

M309.032 is a dedicated outside micrometer designed for five‑point external measurement of three‑ and five‑sided components in production and inspection

• Carbide measuring faces for wear resistance
• Ratchet stop for consistent measuring force
• Precision ±0.005 mm, 0.01 mm reading

High repeatability for production and inspection

The mechanical design delivers repeatable results where process stability matters most. With a reading of 0.01 mm on the thimble and an indicated accuracy of ±0.005 mm, this measuring instrument is tailored to applications that demand reliable tolerances rather than ultra‑fine laboratory resolution. The integrated ratchet stop limits operator variation by applying a constant measuring force, which reduces measurement scatter and speeds up routine control tasks on series parts.

Durable construction reduces downtime

A powder‑coated, enamelled frame combined with a matt‑chrome measuring drum provides resistance against the knocks and oils common in workshop environments. The carbide measuring faces protect the contact surfaces from premature wear when measuring harder materials, extending service intervals and preserving the instrument’s datum accuracy. The compact mechanical layout keeps maintenance straightforward and supports a long service life under regular workshop use.

Built for prismatic and five‑sided components

The instrument is intended for five‑point external measurement of three‑ and five‑sided workpieces, making it suitable for profile and fastener inspection as well as many turned and milled parts. The 25–45 mm range covers an important segment of production parts and complements standard gauge sets, while the 25 mm setting size supports quick switching between nominal sizes during in‑process checks. This balance of reach and stiffness is practical for assembly, fixture and tooling checks in small to medium production runs.

Practical handling and clear results

Operation follows familiar mechanical practice: an easy‑to‑read thimble scale, tactile ratchet feedback and a solid spindle advance, which together make measurements efficient and reproducible on the shop floor. The instrument’s straightforward design reduces operator training time while the robust surfaces and precision mechanics preserve measurement integrity across repeated cycles. Supplied under the Metav IndustryLine label, the unit is positioned as a durable, no‑nonsense tool for routine inspection.

FAQ

What measuring range does this micrometer cover?
The micrometer covers a 25–45 mm measuring range; the Metav IndustryLine M309.032 is intended for close‑range external measurements within that band.

How fine is the reading and what accuracy can be expected?
The thimble provides a 0.01 mm reading and the instrument is specified with an accuracy of ±0.005 mm for reliable workshop control.

Is the instrument suitable for pentagonal and prismatic parts?
Yes, the design is intended for five‑point external checks and is suitable for three‑ and five‑sided workpieces commonly encountered in production.

How does the ratchet stop help measurement quality?
The ratchet stop on the M309.032 ensures a consistent measuring force, reducing operator‑induced variation and improving repeatability for series inspections.

Are the measuring faces durable for harder materials?
The micrometer is fitted with carbide measuring faces, which enhance wear resistance when measuring harder components and support longer service intervals.
