Micrometer Setting Gauge M304.314 — 150 mm reference, ±0.003 mm accuracy (Metav IndustryLine)

The Micrometer Setting Gauge M304.314 is a workshop‑grade calibration reference for outside micrometers, engineered to provide a stable and temperature‑resistant 150 mm standard for repeatable adjustments.

• 150 mm precision reference
• Accuracy ±0.003 mm
• Integrated thermal protection

Precision that keeps production predictable

As a dedicated calibration reference, this setting gauge delivers a clearly defined baseline for outside micrometer adjustment. The combination of a 150 mm nominal length and a certified dimensional tolerance of ±0.003 mm (3 µm) reduces measurement scatter and helps to secure repeatable setups in serial inspection tasks. For quality teams and process engineers, the result is a measurable reduction in rework and inspection uncertainty, translating into more efficient production runs and fewer unexpected rejects.

Designed for stable contact and thermal resilience

The workpiece contact geometry features flat measuring faces mated to an 8 mm contact diameter, providing a concise reference surface that resists tilting during anvil engagement. A built‑in thermal protection layer helps to decouple short‑term temperature fluctuations from the reference dimension, so the gauge maintains its declared figure during normal workshop use. At 0.84 kg the component is easy to position and handle while offering sufficient mass to resist accidental movement during setting procedures.

Practical integration and workplace benefits

As an accessory for outside micrometers, this setting gauge performs the single function of delivering a trusted point of reference for calibration and daily zeroing routines. The robust construction and clear nominal data simplify documentation and traceability in quality records. Technicians will appreciate the concise geometry for rapid micrometer adjustment, and procurement teams will value a compact, easy‑to‑store reference that supports consistent measurement practice across shifts.
