M309.031 5‑point external micrometer — 5–25 mm, 0.01 mm graduation (Metav IndustryLine)

The M309.031 5‑point external micrometer is a robust analogue measuring instrument optimised for precise gauging of five‑sided and polygonal workpieces in workshop and quality‑control environments.

• Five‑point external measuring head
• Measuring range 5–25 mm
• Graduation 0.01 mm
• Carbide measuring faces

Accurate results for small, critical profiles

This analogue micrometer delivers a graduation of 0.01 mm together with a verified accuracy of ±0.005 mm, making it suitable for demanding shop‑floor checks and final inspection tasks. The five‑point measuring head stabilises contact on polygonal faces and reduces alignment errors compared with single‑anvil checks. With its mechanical scale and robust spindle, the instrument provides a direct, no‑battery reading method that is straightforward to interpret and quick to integrate into existing inspection routines.

Consistent contact pressure and wear resistance

Built with a ratchet stop to ensure reproducible measuring force and carbide measuring faces to resist wear, the tool sustains measurement stability over prolonged use. The frame is finished with a painted coating and the measuring drum is matt‑chrome plated, which reduces glare and aids reading under workshop lighting. A factory set setting standard 5 mm facilitates initial calibration and alignment during first use, while the ratchet mechanism helps eliminate variability introduced by hand pressure.

Tailored for polygonal and five‑sided components

Designed specifically for five‑sided and similar polygonal workpieces, the micrometer performs well in toolrooms, production control and specialised mechanical workshops where such shapes are common. The compact envelope and analogue operation support rapid spot checks and batch monitoring without the need for power or digital interfaces, making it a practical choice for throughput‑oriented quality checks and routine machine setup verification.

Procurement confidence and workshop integration

Supplied under the Metav IndustryLine, the instrument benefits from Metav’s established supply chain and product filtration in Emmerich, which supports reliable availability and consistent quality for industrial buyers. Technical identifiers such as GTIN and ETIM classification simplify catalogue management and procurement processes. For customers seeking straightforward, durable measuring technology that integrates with standard inspection workflows, this micrometer combines robustness with the precision required for repeatable results.
