Micrometer Setting Gauge M304.310 — 50 mm, ±0.002 mm (Thermal protection)

The Micrometer Setting Gauge M304.310 is a precision reference standard designed to set and check external micrometres in workshop and inspection environments.

• Precision 50 mm reference
• Accuracy ±0.002 mm
• Thermal protection for stable readings
• Flat measuring faces for repeatability

Reduce inspection time with a reliable reference

The compact setting gauge provides a stable 50 mm reference that shortens calibration and setup routines. With an indicated resolution suitable for fine measurement tasks and an accuracy of ±0.002 mm, the device serves as a true reference standard for external micrometre adjustment. Using a defined master piece minimises iterative adjustments on the production line, which translates into fewer rejected parts and faster changeovers. The light construction keeps handling straightforward without compromising repeatability.

Thermal protection for consistent results in varying environments

Temperature shifts are a common source of measurement drift; the integrated thermal protection reduces heat transfer from hands and ambient sources to the measuring surfaces. As a result, readings remain more stable during repeated use, improving comparability between sequential checks. The flat measuring faces ensure even contact across the reference face, reducing localised deformation and supporting reproducible results when setting micrometre anvils or comparing instrument readings.

Compact format for fine mechanical and precision workshops

Classified in the micro range (10–100 mm), this reference is optimised for fine mechanical applications where compactness and stiffness are essential. Its modest mass of 0.1 kg and slim geometry suit tasks such as watchmaking, precision components and small assembly fixtures where short jaws and low twist contribute to measurement integrity. The gauge is primarily intended as an accessory for external micrometre setting and is easy to store and handle between inspection stations.

Simple integration into quality routines and toolrooms

The master piece supports straightforward procedural integration: use as a go/no-go reference during incoming inspection, as a quick daily check for workshop micrometres, or as a set point for adjusting measuring instruments before critical operations. The accessory nature of the item makes it an efficient addition to tool cabinets and inspection benches, enabling faster verification cycles without large investments.
