M309.350 Disc Anvil Micrometre – 0–25 mm, Ø30 mm disc, ratchet stop (Metav IndustryLine)

The M309.350 Disc Anvil Micrometre is a precision mechanical micrometre for accurate external measurements on small parts in workshop and inspection environments.

• 0–25 mm measuring range
• Ø30 mm disc anvil for stable contact
• Ratchet stop for reproducible measuring force
• Matt‑chrome measuring drum, painted frame

Consistent precision for small‑part inspection

The instrument is built to provide repeatable results when measuring small components. With a measuring span of 0–25 mm, the device sits in the Micro class, offering the ideal balance between compactness and rigidity for fine mechanical work. The specified measurement accuracy of ±0.004 mm and a display resolution of 0.01 mm ensure that dimensional decisions are based on reliable data; the ratchet stop prevents over‑tightening and keeps the applied measuring force consistent, which reduces operator‑induced variation. The Ø30 mm disc anvil increases the contact area for uneven or slightly curved surfaces, improving stability compared with a point anvil.

Rugged design for routine shop use

Durability and ease of handling reduce downtime in production and inspection cycles. A painted frame resists wear on the workshop floor while the matt‑chrome measuring drum gives a glare‑free reading surface. The non‑rotating spindle limits marking on delicate workpieces and helps to preserve surface integrity. At approximately 0.5 kg the gauge remains comfortable for hand inspection yet substantial enough to feel stable during operation. As an analog micrometre it provides a straightforward mechanical reading that requires no batteries, simplifying long‑term use and storage.

Practical applications and measurement benefits

Engineered for external diameter and thickness checks, the micrometre is particularly suited to precision fits, small housings and components where stable contact and repeatability matter most. The wider disc anvil makes it effective for measuring flanges, shallow grooves and parts with limited seating area. Classified in the Micro range, this gauge is appropriate for watchmaking, small‑part assembly, jig and fixture checks, and first‑article inspections where compact footprint and fine resolution are essential. The construction choices—disc anvil, ratchet stop and matt‑chrome drum—translate directly into fewer remeasures and faster inspection throughput.

Supply and assurance from a specialised partner

Sourcing through Metav IndustryLine adds logistical and technical reassurance: centralised stock management in Emmerich supports reliable delivery and access to a broad range of precision tools. Metav’s position as a precision partner means the instrument is offered alongside application advice and spare parts information, helping to integrate the gauge into existing quality‑control routines without unnecessary complexity. The combination of practical workshop durability and consistent measuring force supports both production reliability and quality documentation.

FAQ

Is the micrometre suitable for curved or irregular surfaces?
The Ø30 mm disc anvil of the M309.350 disc anvil micrometre improves seating on slightly curved or irregular surfaces, giving a more stable contact area than a narrow anvil.

What level of repeatability can be expected with this instrument?
Repeatability is supported by the ratchet stop and non‑rotating spindle; typical measurement reproducibility aligns with the stated accuracy of ±0.004 mm when used under consistent handling.

Can the micrometre be used for delicate or finished surfaces?
Yes. The non‑rotating spindle and disc anvil help to reduce marking, making the M309.350 suitable for finished or delicate components where surface preservation is required.

Is this gauge battery‑free and suitable for shop environments?
The device is an analog micrometre and requires no batteries, which simplifies long‑term use in workshop conditions and reduces supply dependencies.

Which workshop tasks is this instrument optimised for?
Optimised tasks include small‑part diameter checks, flange thickness measurement and precision assembly inspection—applications where compact size and stable contact are priorities.
