Single end gauge 2.5 mm — Grade 0 gauge block (Metav IndustryLine)

Single end gauge 2.5 mm for precision reference and verification tasks in metrology and quality control

• Grade 0 accuracy to DIN EN ISO 3650
• Hardened special steel construction
• Nominal size 2.5 mm reference standard
• Lightweight 7 g for easy handling

Traceable accuracy for inspection and setting tasks

The DIN EN ISO 3650 specification ensures this end gauge meets internationally recognised tolerances for gauge blocks. As a Grade 0 reference piece, the element delivers a high level of dimensional certainty suitable for workshop calibration benches and production spot checks. The nominal dimension 2.5 mm is ideal for establishing short-range standards, verifying measuring instruments and cross-checking set-ups on micrometres or comparator stands. The measured tolerance class minimises uncertainty in routine quality control, enabling faster decision-making and fewer re-measurements.

Robust material and compact form for everyday metrology

Manufactured from hardened special steel, this gauge block resists surface wear and retains its geometry under normal workshop conditions. The compact cross-section (applicable up to 10 mm: 30 x 9 mm) gives a stable contact face and simplifies positioning in fixtures or between anvils. The small mass (approx. 7 g) and firm geometry reduce handling-induced error during short measurements, translating into efficient use on the shop floor and in inspection rooms. This combination of material and form supports repeatable results without the need for elaborate handling equipment.

Practical use and care to extend service life

As a single reference element, the gauge is straightforward to incorporate into daily routines for verification, machine set-up and instrument comparison. Routine care—cleaning contact faces with lint-free cloth and suitable solvent, storing in a dry case and avoiding hard impacts—preserves the calibrated surface over time. Where multiple reference sizes are required, keeping a set of matched end gauges simplifies traceability chains and reduces downtime for recalibration. The robust finish of the part makes maintenance simple while supporting long-term dimensional stability.
