M309.252 Disc-Anvil Micrometer, 50–75 mm, Ø20 mm — Metav IndustryLine

The M309.252 disc-anvil micrometer is a precision mechanical instrument for workshop and inspection use, designed for repeatable measurements of flat and slightly profiled surfaces within the 50–75 mm range.

• High-precision ±0.005 mm accuracy
• Disc anvil Ø20 mm for flat surfaces
• Non-rotating spindle with ratchet stop
• Delivered in protective transport case

Reliable measurement performance for production control

Equipped with a finely graduated thimble and a rated accuracy of ±0.005 mm, this analogue micrometer delivers consistent results for routine quality checks and dimensional control. The engraved scale provides a 0.01 mm readout, while the ratchet stop limits applied measuring force to reduce operator-induced variation. Together with the non-rotating spindle, these features minimise wear on the workpiece and deliver stable repeatability, making the tool suitable for shop-floor inspection and routine process monitoring in metalworking and toolmaking.

Robust design that supports fast, ergonomic handling

The instrument combines a painted frame with a matt-chrome plated measuring drum, offering a durable surface finish that resists everyday knocks and contamination. The Ø20 mm disc anvil spreads contact pressure and stabilises readings on flat components, while a compact mass of 0.8 kg keeps the micrometer easy to manoeuvre during repetitive tasks. Delivery includes a protective transport case to safeguard the instrument between uses and during transport, improving service life and reducing downtime for maintenance or replacement.

Practical fit for workshop and inspection environments

With a measuring range of 50–75 mm, this micrometer covers medium-sized parts typical in general machining, fixture production and component assembly. The mechanical construction supports straightforward use without electronics, which simplifies maintenance and long-term reliability in harsh workshop conditions. As part of the Metav IndustryLine, the instrument is identified by GTIN 4054469118710 and SKU M309.252, ensuring traceability and straightforward stock management for procurement and calibration planning.

FAQ

What measuring range does this micrometer cover?
The M309.252 covers a measuring span of 50–75 mm, suitable for medium-sized components commonly found in machining and assembly.

How precise is the device and what is the readout?
The instrument has an accuracy of ±0.005 mm with a readout graduation of 0.01 mm for clear analogue measurement.

Why is the non-rotating spindle important?
A non-rotating spindle prevents surface scuffing on the workpiece and improves repeatability; this feature is incorporated in the M309.252 for reliable flat-surface checks.

What benefit does the Ø20 mm disc anvil provide?
The disc anvil increases contact area on flat or thin-walled parts, reducing local deformation and yielding more stable measurements.

Is the micrometer supplied ready for transport?
The M309.252 is supplied in a protective transport case to ensure safe handling and storage between uses.
