Precision setting gauge M304.316 — 200 mm reference, ±3.5 µm accuracy, thermal protection (Metav IndustryLine)

Precision setting gauge M304.316 provides a compact and robust reference for setting external micrometers and verifying measuring equipment in production and calibration environments.

• 200 mm reference length
• ±3.5 µm setting accuracy
• Integrated thermal protection
• Flat measuring faces, compact handling

Consistent reference and measurable accuracy for production control

The M304.316 acts as a stable reference standard for external micrometer adjustment, offering a nominal length of 200 mm and a stated accuracy of ±0.0035 mm (±3.5 µm). This level of precision supports reliable zeroing and verification of micrometers used in quality control and routine setup. By converting manufacturer tolerances into a reproducible baseline, the gauge reduces rework and contributes directly to process reliability and throughput.

Thermal protection that stabilises readings in shop conditions

Equipped with thermal protection, the gauge is designed to mitigate the effects of temperature differences between tool, workpiece and operator—common causes of drift in small-length references. The heat-shielding feature helps maintain dimensional stability during transfer from storage to the workbench and while taking successive settings, improving repeatability when conditions vary across shifts or machines.

Practical geometry and handling for fast workstation use

The device features flat measuring faces and a compact form factor with a diameter of 8 mm on the reference shank and a mass of 0.2 kg, enabling steady handling and secure seating in micrometer anvils. Its balanced weight and face design simplify alignment and minimise rocking during engagement, so setup time is shortened and the risk of measurement artefacts from operator handling is reduced.

Designed for workshop and calibration tasks

Built as an accessory for micrometer adjustment, this reference is suited to maintenance shops, production lines and calibration benches where quick, repeatable checks are required. The robust construction and clear dimensional definition let production teams and metrology technicians implement consistent setting routines that support traceable quality management and minimise measurement-related stoppages.
