Setting gauge for micrometres M304.320.9 — 675 mm nominal, ±0.007 mm accuracy (Metav IndustryLine)

The Setting gauge for micrometres M304.320.9 is a long-range setting standard designed to set and verify outside micrometres for large components, combining a 675 mm nominal length with thermal protection for stable references.

• Setting standard 675 mm nominal length
• High accuracy ±0.007 mm calibration
• Thermal protection for stable measurements
• Ball-shaped measuring faces for repeatability

Precision for large-format setups

The gauge delivers a nominal length of 675 mm and a guaranteed accuracy of ±0.007 mm (7 µm), placing it in the large-range class (500–1,000 mm) suitable for big assemblies and long measuring tasks. This level of precision reduces setup uncertainty when adjusting outside micrometres and shortens downstream inspection cycles. The design supports reproducible length references across production batches, making it a rational choice where dimensional conformity directly affects part interchangeability.

Thermal protection reduces measurement drift

Integrated thermal protection minimises the influence of ambient temperature fluctuations during setup and short verification tasks. For long-format gauges, even small temperature variations can introduce measurable expansion; the thermal shield reduces that effect and therefore lowers the risk of drift during short-term handling. The result is more consistent readings from the reference surface to the gauge, translating into fewer corrective operations and steadier process control on the shop floor.

Practical handling and repeatable contact

The measuring faces are ball-shaped, providing defined point contact that eases alignment with micrometre anvils and reduces local surface sensitivity. At a weight of 1.1 kg, the standard remains portable for bench-top use while offering sufficient mass for stable positioning. The compact cross-section (measuring face diameter 16 mm) simplifies engagement with micrometre anvils and helps achieve repeatable contact conditions, which in turn makes routine setting faster and less operator-dependent.

Built for workshop workflows and traceable output

Manufactured as an accessory-grade reference, the gauge is suited to quality assurance loops where a consistent setting standard is required before batch runs or assembly checks. The combination of defined contact geometry and thermal shielding supports continuous use in machine shops, tool rooms and calibration benches. Documentation of the gauge’s characteristics (nominal length, declared accuracy and part identification) helps integrate it into inspection plans and traceability records without overcomplication.
