Setting Gauge for Micrometers M304.320.6 — 525 mm, ±0.006 mm accuracy

The Setting Gauge for Micrometers M304.320.6 is a precision reference rod designed for the calibration and adjustment of outside micrometers in workshop and laboratory environments

• 525 mm nominal length for extended reach
• Accuracy ±0.006 mm for high-precision setting
• Thermal protection reduces heat transfer errors
• Ball-ended measuring faces for repeatable contact

Precision where measurement stability reduces rework

The gauge provides ±0.006 mm accuracy (equivalent to 6 µm), a level of precision that removes guesswork when setting or checking outside micrometers. This resolution translates into measurable improvements in process control: a stable reference at this tolerance allows repeat adjustments to be made with confidence and reduces the need for corrective machining. The long nominal span of 525 mm supports applications beyond small parts, enabling checks on longer components or assemblies while maintaining a compact handling profile. The specified tolerance is expressed in absolute terms so that decision-making for quality control can be based on objective criteria rather than operator feel.

Stable results in workshop conditions through thermal and contact design

The instrument incorporates thermal protection, which limits heat transfer from hands and the environment and so reduces systematic measurement drift during repeated use. Combined with ball-ended measuring faces, this design ensures a single, well-defined contact point that reduces variability caused by slight angular misalignment. The listed mass of 0.8 kg provides enough inertia for steady placement while keeping the gauge easily manoeuvrable for one-person operation. Together, these elements support reproducible setups and faster throughput in routine inspection or during tool calibration cycles, emphasising reliable results under normal shop-floor conditions.

Efficient calibration workflow and practical compatibility

Designed as an accessory for setting outside micrometers, the reference rod streamlines the calibration workflow and simplifies the transfer of a length standard into hand-held instruments and comparators. The combination of length, contact geometry and thermal control reduces setup time and the number of iterative checks before sign-off. The model is supplied as a ready accessory with the commercial identification M304.320.6 and is suitable for use where a stable, long reference is required to align micrometric measuring tools or to verify linear adjustments on fixtures and gauges.

FAQ

What accuracy can be expected from this setting gauge?
The setting gauge provides an accuracy of ±0.006 mm (6 µm), which is suitable for high-precision adjustment and verification tasks where micrometric tolerances are required.

Which nominal length does the gauge offer and what is it used for?
The nominal length is 525 mm; the gauge is intended as an accessory for setting and checking outside micrometers and for transferring a stable length reference in workshop or laboratory contexts.

How do the ball-ended measuring faces influence measurement repeatability?
The ball-ended measuring faces create a defined point contact that compensates for minor angular misalignment and improves repeatability by reducing the contact variability typical of flat or irregular contact surfaces.

What is the role of the thermal protection feature?
The thermal protection reduces heat transfer from hands and the environment to the reference body, lowering systematic drift during repetitive handling and improving consistency in successive measurements.

Is this model identified by a specific SKU or code?
Yes, the product is listed under the article number M304.320.6 and carries GTIN 4054469116754 for unambiguous procurement and inventory tracking.
