Single gauge block 7.5 mm — Grade 0, DIN EN ISO 3650 (Metav IndustryLine)

The Single gauge block 7.5 mm is a hardened precision reference intended for traceable length standards, master measurements and high-accuracy setting operations in metrology and quality control environments.

• DIN EN ISO 3650 Grade 0 accuracy
• Hardened special steel construction
• Compact reference for precision calibration

Stable reference for reproducible measurements

This gauge is manufactured to DIN EN ISO 3650 and supplied in Grade 0, making it suitable where a stable, high-accuracy reference is required. The block’s nominal size 7.5 mm and precisely machined faces provide a repeatable contact surface for comparisons and stack-based length standards. As a hardened reference in special steel, it limits wear and dimensional drift over time, which reduces the need for frequent retesting and maintains measurement integrity in inspection routines.

Robust material and compact geometry for handling

Constructed from hardened special steel, the unit combines surface stability with practical handling characteristics. The cross-sectional profile of 30 × 9 mm for sizes up to 10 mm gives good stiffness relative to its size, minimising bending and improving contact repeatability during stacking or single-block use. The compact format also simplifies storage and short-distance transport within a laboratory, while the hardened finish offers resistance to light knocks and common workshop influences.

Application benefits and practical use cases

As a precision reference, this block is ideal for transfer standards, gauge stacks, and setting tools where quick, reliable verification of small lengths is needed. The accurately lapped faces ensure consistent seating against gauges, pins or measuring machine anvils, enabling efficient calibration workflows in both production and test labs. For smaller instrument adjustments and master-setting tasks, the compact block permits one-handed positioning and rapid integration into measurement routines.

Quality assurance and procurement confidence

Sourcing this unit under the Metav IndustryLine label provides an additional assurance of supply-chain oversight and selection for professional users. The combination of an established standard (DIN EN ISO 3650) and hardened special-steel construction supports long service life and dependable in-use performance. For procurement and inventory planning, the clear specification and compact footprint help standardise master references across inspection benches and workstations.
