M304.053 Micrometer — Counting dial, 50–75 mm, 0.01 mm (Metav IndustryLine)

The M304.053 is a precision outside micrometer with a counting dial, built for accurate measurement of medium-sized components in workshop and inspection environments.

• Counting dial with 0.01 mm resolution
• Ratchet stop for consistent measuring force
• Hardened measuring faces for long life
• Matt chrome-plated measuring drum

Precision where clear readings save time

The instrument delivers a resolution of 0.01 mm, making it suitable for routine inspection tasks that require sub‑hundredth millimetre accuracy. The integrated counting dial simplifies multi‑turn readings by indicating full revolutions of the thimble, which reduces reading errors and speeds up measurement of larger increments. Compliance with DIN 863 ensures the measuring concept and scale graduations follow recognised workshop standards, providing a predictable basis for quality control and process documentation.

Repeatable force for reliable results

Equipped with a ratchet stop, the micrometer ensures a controlled contact pressure during each measurement. This mechanical regulation prevents over‑tightening and minimises variation between operators, which improves repeatability across a production batch. The spindle has a 0.5 mm pitch, combining sensible tactile feedback with fine adjustment, while a 6.5 mm spindle diameter gives sufficient stiffness for stable contact under normal workshop use.

Built to withstand workshop conditions

Critical wear surfaces are hardened, so the measuring faces resist abrasion and preserve accuracy over prolonged service life. The matt chrome‑plated measuring drum reduces glare and improves legibility in varied lighting conditions, while the robust construction and an overall weight of 0.75 kg give a reassuring, durable feel at the bench. The instrument is analog, which many inspection routines prefer for direct, battery‑free operation and simple integration into existing workflows.

Suitable range and typical applications

With a measuring span of 50–75 mm, this instrument covers shafts, bosses and medium‑sized machined parts commonly found in toolmaking, jigs and fixtures, and general engineering. The combination of 0.01 mm resolution, mechanical counting and hardened contact faces makes it a practical choice where straightforward, repeatable measurements are required without the need for digital data output.

FAQ

How precise is the M304.053 for routine inspection tasks?
The M304.053 provides a 0.01 mm resolution suitable for standard workshop inspections and quality checks where sub‑hundredth millimetre differentiation is required.

Does the instrument prevent measurement variability between operators?
Yes, the incorporated ratchet stop on the M304.053 enforces a consistent measuring force, reducing operator‑to‑operator variation and improving repeatability.

Are the measuring faces durable for daily use?
The measuring faces are hardened, which protects against wear and ensures maintained accuracy over frequent use in production and inspection environments.

What kind of components is the 50–75 mm range best for?
The 50–75 mm span is ideal for medium‑sized shafts, collars, housings and machined features commonly encountered in toolmaking and general engineering, where a compact, precise instrument is needed.
