End gauge 1.39 mm — DIN EN ISO 3650 Grade 0, hardened special steel (Metav IndustryLine)

The End gauge 1.39 mm is a precision reference intended for dimensional verification and calibration tasks in metrology laboratories and production quality control.

• DIN EN ISO 3650 compliant Grade 0
• Hardened special steel construction
• Precise nominal size 1.39 mm
• Compact, low-mass inspection gauge

Measurable accuracy for dependable inspection results

The item serves as a traceable reference for dimensional checks where consistent, repeatable results are required. Manufactured to DIN EN ISO 3650 and specified as Grade 0, this gauge offers one of the tightest tolerances within the standard series, making it well suited for high‑precision verification of micrometric settings and gauge comparisons. The nominal dimension of 1.39 mm is finished and tested to provide a reliable datum for comparator setups and reference stacks. By using a standardised end gauge rather than improvised masters, inspection processes become more defensible and easier to document, supporting internal quality procedures and external audits.

Long-term stability through material choice and geometry

Constructed from hardened special steel, the gauge resists wear and preserves its geometry under normal handling and routine use. The compact cross‑section of 30 × 9 mm (applicable for nominal sizes up to 10 mm) reduces bending moment and thermal mass, which helps to keep dimensional shifts small during brief temperature changes and handling. With a mass of approximately 6 g, the part is easy to position and manoeuvre without compromising contact stability. These design choices minimise the frequency of reworking reference standards and reduce the risk of cumulative error when stacking or comparing multiple master gauges.

Practical integration into calibration and production workflows

As a single end gauge, the component is straightforward to incorporate into existing inspection routines: it can be used as a reference in comparator benches, as a check standard for micrometres and bore gauges, or as part of master sets for incoming inspection. The simple geometry eases cleaning and handling procedures, while the robust surface finish supports repeated contact with measuring anvils. Documentation and traceability are facilitated by the clear nominal marking and the product’s adherence to a recognised norm, which aids cross‑departmental communication and the maintenance of inspection rigs. For organisations seeking to raise the reliability of their dimensional controls, this reference element is a practical, low‑effort improvement with measurable benefits.

FAQ

What does Grade 0 mean for this end gauge?
Grade 0 indicates one of the highest accuracy classes defined in DIN EN ISO 3650 and signifies that the end gauge meets stringent dimensional and surface requirements for use as a reference standard.

Can this end gauge be used as a master for comparator setups?
Yes. The 1.39 mm end gauge from Metav IndustryLine is intended as a stable reference for comparator benches and for checking measuring instruments where a precise nominal dimension is required.

How should the gauge be handled to preserve accuracy?
Handle the hardened special steel gauge with clean, dry hands or gloves and avoid unnecessary impacts; keep it in a protective environment when not in use to maintain the surface condition and dimensional integrity.

Is this end gauge suitable for stacking with other precision gauges?
The gauge’s compact geometry and Grade 0 accuracy make it suitable for inclusion in master sets and controlled stacks, provided stacking procedures follow best practices to avoid excessive side forces.
