End gauge 7.5 mm — DIN EN ISO 3650 Grade 1, hardened special steel (Metav IndustryLine)

The End gauge 7.5 mm is a precision reference block for dimensional inspection and calibration tasks in quality control, designed for use in metrology laboratories and workshop inspection stations

• DIN EN ISO 3650 Grade 1 tolerance
• Hardened special steel construction
• Compact 7.5 mm certified end gauge

Certified dimensional standard for dependable inspection

The end gauge serves as a certified reference for setting, checking and calibrating measuring instruments. Manufactured to DIN EN ISO 3650 and held to Grade 1 tolerances, the block provides a reproducible nominal length of 7.5 mm that supports consistent quality control routines. Using a standardised reference reduces uncertainty in downstream measurements, enabling faster decision-making in production and QA workflows while meeting common industrial inspection criteria.

Robust material and geometry for stable results

Constructed from hardened special steel, the gauge offers high wear resistance and low susceptibility to surface damage that can compromise accuracy. Its compact cross-section (30 × 9 mm for sizes up to 10 mm) ensures minimal bending and thermal mass, which helps preserve dimensional stability in typical workshop environments. The low mass (approx. 0.01 kg) simplifies handling while the uniform geometry supports repeatable contact conditions during verification tasks, contributing to reliable, long-term measurement performance.

Practical use and traceability in inspection chains

As a traceable reference, the block integrates smoothly into calibration routines and inspection plans where a fixed nominal length is required for setting comparators, checking micrometres or verifying gauge block stacks. The compact format makes it especially convenient for bench-top use or as a portable standard within a calibrated set. Clear conformity to the standard streamlines documentation and reassures procurement and quality teams that the reference aligns with accepted metrological practice.
