Gauge block 20.5 mm — DIN EN ISO 3650 Grade 1 (Metav IndustryLine)

The Gauge block 20.5 mm is a precision reference standard for dimensional verification and calibration in workshops and inspection labs.

• DIN EN ISO 3650 Grade 1 accuracy
• Hardened special steel construction
• Nominal size 20.5 mm precisely ground
• Compact, workshop-ready gauge block

Reduce measurement uncertainty with a certified reference

Achieve consistent inspection outcomes with a DIN EN ISO 3650 Grade 1 reference that minimises traceable measurement uncertainty. The 20.5 mm nominal size is ground and lapped to tight tolerances, providing a reliable benchmark for setting calipers, micrometres and comparators. Specifying a Grade 1 block supports repeatable dimensional decisions and reduces scrap and rework by ensuring instruments are checked against a stable, standardised artefact.

Robust construction for durable shop-floor use

Built from hardened special steel, the block resists wear and maintains flatness and parallelism during regular handling. The cross-section specification for sizes above 10.1 mm (35 x 9 mm) delivers the stiffness required to avoid bending during use, while the compact mass supports easy handling and storage on inspection benches. This combination of material and form factor prioritises long service life and consistent dimensional stability in daily quality control routines.
