Setting gauge for micrometers M304.320.7 — 575 mm, ±0.006 mm accuracy (Metav IndustryLine)

The Setting gauge for micrometers provides a rigid 575 mm reference length designed for precise adjustment of external micrometers and repeatable workshop checks.

• 575 mm nominal length, rigid reference
• ±0.006 mm (6 µm) measurement accuracy
• Spherical measuring faces with thermal protection

Consistent precision for production and inspection

The gauge delivers highly repeatable readings thanks to an accuracy of ±0.006 mm (6 µm) and a long, stable reference length of 575 mm. This level of precision supports quality-assurance routines where micrometers must be set to a known standard prior to batch inspection or process checks. By providing a clear nominal length and defined tolerance, the gauge reduces variability that would otherwise arise from informal setting methods, improving throughput in calibration and measurement loops while maintaining compliance with typical workshop tolerances.

Thermal stability and reliable contact geometry

Built with thermal protection, the gauge minimises the influence of ambient temperature changes on the reference length, which is particularly important at longer sizes. The spherical measuring faces ensure consistent point contact with micrometer anvils, lowering the risk of misalignment or edge contact that can bias a setting. A compact stem of 16 mm diameter aids in guided contact and repeatability, while the overall design prioritises stable seating during adjustment operations.

Suited to larger workshop ranges and streamlined workflows

Classified as a Large-range gauge (500–1,000 mm), the reference length covers larger micrometer ranges and simplifies inventory by replacing multiple shorter standards. At a weight of 0.9 kg, the gauge is manageable for single-person handling while still providing the mass necessary for steady placement. Integrating the gauge into routine setup reduces adjustment time for production lines and supports consistent measurement practices across shifts, contributing to faster machine changeovers and fewer rejected parts.

Practical handling, traceability and workshop use

The accessory is intended as a calibrated reference length for setting external micrometers and for regular bench checks. The combination of 575 mm nominal length, defined ±0.006 mm tolerance and pragmatic handling features supports traceability in inspection logs and can be incorporated into existing calibration routines. The compact footprint and straightforward geometry make it a practical addition to the metrology bench where dependable, repeatable micrometer settings are required.

FAQ

Is the gauge suitable for setting all external micrometers?
The setting gauge for micrometers is intended as a 575 mm reference standard and is suitable for setting external micrometers whose range or anvils can be referenced to that length; consult the specification of individual micrometers for compatibility.

What level of precision does the reference provide?
The Metav IndustryLine setting gauge M304.320.7 provides an accuracy of ±0.006 mm (6 µm), which supports fine adjustment and repeatable reference points for workshop and inspection uses.

How does the thermal protection affect measurements?
Thermal protection reduces the impact of ambient temperature changes on the reference length, helping to maintain the 575 mm nominal value within the specified ±0.006 mm tolerance during routine bench operations.

What advantages do spherical measuring faces offer?
Spherical measuring faces provide consistent point contact with micrometer anvils, lowering alignment errors and improving repeatability when establishing reference settings.

Is calibration documentation included with the gauge?
Product data does not specify an ISO 17025 certificate by default; for information on calibration documentation and available certification options, please contact Metav Werkzeuge.
