M304.240 Outside Micrometer Set — 0–100 mm, 4‑piece, friction ratchet | Metav IndustryLine

A robust M304.240 outside micrometer set designed for accurate external measurements across 0–100 mm, supplied as a four‑piece kit in a protective cassette

• Friction ratchet for repeatable measuring force
• 0.01 mm graduation for precise readings
• Satin chrome‑plated measuring drum for durability
• Comprehensive 4‑piece set with setting standards

Precision that reduces rework and inspection time

The set is an analog micrometer family that delivers a 0.01 mm reading by combining a spindle pitch 0.5 mm with fine thimble graduations, which equals 0.01 mm per division. This mechanical arrangement provides a direct, tactile measurement method that is easy to verify and calibrate. Conformity with DIN 863 ensures the instruments meet recognised workshop standards, making them suitable for routine dimensional checks where traceable, repeatable readings are required. The clear graduations and satin finish on the measuring drum reduce parallax and glare, aiding consistent interpretation of results.

Consistent measuring force for reliable results

A built‑in friction ratchet controls the applied measuring pressure and reduces operator‑related variability during the final approach. This feature is particularly valuable when multiple operators inspect identical parts or when short‑term repeatability is critical to maintain process capability. The micrometer spindle uses a conventional 6.5 mm diameter design and the measured mechanical arrangement is optimised for stable axial movement; as a result, measurements show lower scatter under normal workshop handling. The analogue mechanism also allows immediate verification and maintenance without electronic dependencies.

Practical kit layout that supports workshop efficiency

Supplied as a 4‑piece set with setting standards at 25 / 50 / 75 mm, the instruments cover the common measurement intervals used in production and inspection. Each micrometer is housed in a purpose‑made cassette for organised storage and safe transport between workstations. The satin chrome‑plated measuring drum resists wear and provides a tactile, low‑reflection surface that keeps scales legible over time. Together, the modular design and exchangeable sizes reduce tool changes and speed up inspection cycles on the shop floor.

Built for everyday workshop use and straightforward maintenance

As an analog solution, the instruments are mechanically simple to service; routine checks include cleaning the spindle faces, verifying the setting standards and ensuring the ratchet mechanism remains free of debris. The DIN 863 reference and the robust surface plating make these micrometers a practical choice for environment‑tolerant inspection points in machine shops and maintenance departments. The set format also streamlines inventory control and allows teams to match the right micrometer to the task without delay.

FAQ

What measuring range does the set cover?
The set covers an external measuring range from 0 to 100 mm with four instruments that step through the standard intervals.

What resolution and graduations are provided?
Each micrometer offers a 0.01 mm graduation, achieved with a 0.5 mm spindle pitch combined with fine thimble divisions.

How is consistent measuring force achieved?
A built‑in friction ratchet provides a uniform end‑stop torque to reduce variation caused by differing operator pressure.

Is the set suitable for everyday workshop inspection?
Yes, the kit conforms to DIN 863 and is designed for routine dimensional checks in production and maintenance environments.

What does the cassette provide?
The cassette organises the four instruments and their setting standards, protecting them from impact and making storage and transport straightforward.
