Single gauge block 4.5 mm — precision end gauge, Grade 0

A single end gauge designed as a stable dimensional reference for calibration benches and laboratory checks across mechanical workshops and toolrooms.

• DIN EN ISO 3650 Grade 0 accuracy
• Hardened special steel construction
• Precision reference for calibration benches

Certified reference for repeatable dimensional control

The single gauge block provides a verifiable reference at 4.5 mm with a tolerance class of Grade 0 according to DIN EN ISO 3650, making it suitable for high-precision calibration tasks. Manufactured from hardened special steel, the piece resists wear and preserves its measuring face under regular use, ensuring long-term dimensional stability. The standard conformity offers a clear technical basis for traceability in quality systems and makes this reference suitable for use on calibration benches and in inspection labs where repeatability and documented compliance are essential.

Compact form factor that supports efficient workshop workflows

Designed with a compact cross-section of 30 x 9 mm (applicable for sizes up to 10 mm), the component balances stiffness and handling for everyday workshop routines. The short, robust profile minimises tilting during placement and eases stacking with other reference pieces when setting micrometres, calipers or measuring machines. The small mass and proven geometry reduce the influence of thermal gradients during short handling times, so set-up and verification cycles remain efficient without sacrificing measurement confidence.

Built for quality assurance and process stability

As a precision reference, the gauge piece supports internal quality assurance processes by providing a stable baseline for verifying measuring instruments and fixtures. Its standardised dimensions and material choice reduce rework and measurement uncertainty when used as part of a calibration plan. Combined with Metav’s commitment to accessible precision and distribution from Emmerich, the product strengthens process reliability in production and maintenance environments, helping to maintain consistent tolerances across batches and assemblies.
