Single gauge block 21 mm — DIN EN ISO 3650 Grade 0, hardened special steel (Metav IndustryLine)

The Single gauge block 21 mm serves as a high-precision reference for calibration and measurement tasks, ideal for forming gauge stacks and checking dimensional standards in workshop and inspection settings.

• DIN EN ISO 3650 Grade 0 accuracy
• Hardened special steel construction
• Nominal length 21 mm for precision stacks
• Cross-section 35×9 mm for rigid handling

Traceable accuracy for routine and lab use

The block is manufactured to DIN EN ISO 3650 and specified as Grade 0, providing a clearly defined tolerance class for reference measurements. As a compact reference element with a 21 mm nominal length, it is suitable for assembling gauge stacks or checking the setting of measuring instruments. The standard conformity ensures that the deviation band and manufacturing tolerances meet recognised metrological criteria, which supports consistent, comparable results across instruments and shifts in production.

Robust construction that preserves geometry

Made from hardened special steel, the block resists wear and maintains its geometry under regular handling. The larger cross-section specified for this size—35×9 mm—delivers increased stiffness compared with smaller-section blocks, reducing the risk of bending during placement and improving repeatability when used in stacks. This rigidity translates into fewer re-measurements and a lower incidence of handling-induced error, which is particularly relevant in busy shop-floor situations.

Easy integration into measurement routines

Designed as a single end standard, the block integrates smoothly into existing calibration and measurement workflows. It is suitable for building gauge stacks, verifying micrometer and caliper settings, and serving as a reference for height gauges and other dimensional equipment. The compact nominal length aids manoeuvrability when assembling stacks or measuring small components, while the standardised form factor simplifies compatibility with holders and accessories commonly used in inspection labs.

Reliability backed by a focused supplier

Metav IndustryLine positions this block as a workshop-proven reference that reflects the company’s focus on accessible precision. The construct and compliance with international norms make it a practical choice for quality departments and toolrooms that require dependable reference standards without excessive logistical overhead. Metav’s distribution and quality processes support consistent supply and clear product identification for traceable inventory management.

FAQ

What level of accuracy does this gauge block offer?
The Metav IndustryLine single gauge block 21 mm conforms to DIN EN ISO 3650 Grade 0, providing the specified tolerance class required for traceable reference measurements.

Which material is used for this block and why does it matter?
Manufactured from hardened special steel, the block offers excellent wear resistance and dimensional stability, which preserves measurement geometry during regular workshop use.

Can this block be used in gauge stacks and for calibrating other instruments?
Yes. The 21 mm nominal length and standardised form make the block suitable for building gauge stacks and for checking micrometer, caliper and height-gauge settings.

How does the cross-section affect handling and repeatability?
The 35×9 mm cross-section for sizes above 10.1 mm increases stiffness and reduces bending, improving handling repeatability and lowering the chance of handling-induced measurement error.

Is this gauge block suitable for both workshop and inspection-laboratory environments?
Yes, the combination of DIN EN ISO 3650 conformity and hardened construction makes the block appropriate for workshop calibration tasks and for use as a traceable reference in inspection environments.
