M304.321.2 — 775 mm setting gauge for outside micrometers with heat protection

M304.321.2 is a precision setting gauge designed to set and verify outside micrometers in production and inspection environments, offering a long measuring range with features that reduce thermal and contact-related measurement errors.

• 775 mm nominal length
• High accuracy ±0.008 mm
• Ball-shaped measuring faces
• Integrated heat protection

Precision that remains consistent over long spans

The setting gauge delivers a ±0.008 mm accuracy across its 775 mm nominal length, which makes it suitable where reproducible reference values are required for micrometer adjustment. The ball measuring faces reduce local deformation at the contact points and simplify centring on cylindrical parts, while the solid 16 mm diameter shaft contributes to structural stability. With a mass of 1.3 kg, the unit resists inadvertent movement during setup, translating into fewer re-measurements and a more efficient calibration routine.

Designed for workshop and production environments

Classified as a large-range (500–1,000 mm) setting instrument, this gauge is intended for use in machine shops, fixture assembly and quality-control benches where extended reach and stiffness are both required. The tool functions as a straightforward reference for setting outside micrometers and is particularly helpful when working with longer spindles, jaws or large workpieces that exceed typical bench gauges. The nominal geometry and handling characteristics reduce the time needed for micrometer adjustment and help maintain process throughput.

Built-in thermal protection and trusted provenance

Thermal effects are a common source of drift in dimensional work; the integrated heat protection minimises influence from operator contact and ambient temperature fluctuations, supporting stable settings across shifts. Supplied with ball-shaped contacts to limit local distortion, the instrument supports repeatable results during serial setups. As part of the Metav IndustryLine, the gauge benefits from an established European supply chain that focuses on accessible precision and dependable delivery, reinforcing reproducibility at the workshop level.
