Setting gauge for micrometers M304.312 — 100 mm, accuracy ±2.5 µm

The Setting gauge for micrometers M304.312 is a compact reference used to set and verify external micrometer heads in inspection and workshop environments

• 100 mm reference gauge
• High accuracy ±2.5 µm for repeatable adjustments
• Flat measuring faces with 8 mm diameter

Stable reference for precise micrometer adjustment

This reference standard provides a 100 mm nominal measure with a declared resolution of 0.0025 mm (equivalent to ±2.5 µm), making it suitable where tight tolerances matter. As a dedicated setting gauge it shortens setup time by offering a single, traceable dimension for spindle and anvil alignment. The high repeatability of the reference reduces measurement scatter when calibrating external micrometers, which leads to fewer rejects and more consistent production outcomes.

Design that mitigates thermal influence and ensures contact integrity

The component includes thermal protection, which limits temperature-induced length changes during typical workshop handling. Combined with flat measuring faces and an 8 mm diameter contact zone, the geometry promotes full and repeatable contact between the gauge and the micrometer anvils. The compact mass (approx. 0.1 kg) reduces thermal inertia while keeping the gauge easy to position, so the stability of the reference is preserved during short adjustment procedures.

Practical use and integration into inspection workflows

Classified as measuring accessories, this 100 mm reference is intended for routine setting of external micrometer spindles and can be stored alongside other bench standards. Its compact format fits standard inspection benches and enables clear, fast transfer of the nominal value to a micrometer head. As an accessory in the Metav IndustryLine range, the gauge supports standard workshop and inspection tasks where a concise, durable reference dimension is required.
