M304.320.5 — Setting Gauge for Micrometers, 475 mm with Thermal Protection

The M304.320.5 is a precision setting gauge designed for adjusting external micrometers and reference measurements in workshop and calibration environments.

• Accuracy ±0.005 mm (5 µm)
• Nominal length 475 mm for extended range
• Thermal protection for stable readings
• 16 mm diameter for solid contact

Precision where consistent reference matters

The primary purpose of this reference rod is to provide a stable, verifiable standard for setting external micrometers. With an accuracy of ±0.005 mm (5 µm) and ball-shaped measuring faces, the gauge reduces alignment and contact errors that otherwise introduce traceable uncertainty. The thermal protection minimises expansion effects during routine workshop use, so adjustments stay reproducible across shifts. This translates into fewer rechecks, faster setup cycles and a measurable improvement in process reliability.

Geometry and handling tuned for workshop routines

At 475 mm nominal length the gauge sits in the medium class for reference tools, offering an excellent balance between reach and rigidity. The solid 16 mm diameter gives a stable contact area for larger micrometer anvils while the ball-shaped measuring faces ensure repeatable point contact without lateral play. Weighing approximately 0.7 kg, the unit is easy to position by one operator yet substantial enough to resist incidental movement, which supports faster and more confident measurement routines on the shop floor.

Confidence from a traceable supplier network

As an accessory category item from Metav IndustryLine, the gauge benefits from a distribution and quality filter established in Emmerich. That provenance means clear stock visibility and dependable delivery for production-critical tooling. For workshops seeking to standardise micrometer setup and reduce scrap, the reference rod offers both the technical specification and the dealer support that make implementation straightforward. For further clarification on compatibility with existing micrometers, technical specialists are available to advise.

FAQ

What is the intended use of this setting gauge?
The setting gauge M304.320.5 is intended as a reference for adjusting external micrometers and for routine comparative checks in workshops and calibration benches.

How precise is the reference and what does ±0.005 mm mean in practice?
An accuracy of ±0.005 mm (5 µm) means the reference will keep micrometer settings within a few micrometres of the nominal value, suitable for precision workshop and quality-control tasks.

Does the gauge tolerate temperature changes on the shop floor?
The thermal protection integrated into the M304.320.5 reduces the effect of ambient temperature fluctuations and helps to maintain stable reference dimensions during normal workshop operations.

Are the measuring faces suitable for different micrometer anvil geometries?
The ball-shaped measuring faces provide repeatable point contact and are compatible with a wide range of external micrometer anvils for consistent adjustments.

Which length class does a 475 mm nominal length correspond to and what is the benefit?
A 475 mm nominal length places the gauge in the medium class (300–500 mm), offering a compromise between reach and stiffness that is ideal for larger micrometers and common workshop assemblies.
