End gauge 1.21 mm — Grade 1, DIN EN ISO 3650 (Metav IndustryLine)

The End gauge 1.21 mm is a precision inspection gauge for dimensional verification and calibration tasks in metrology and manufacturing.

• DIN EN ISO 3650 Grade 1 tolerance
• Hardened special steel construction
• Compact mass: 0.005 kg for stable handling
• Cross-section 30 x 9 mm for sizes ≤ 10 mm

Precision that supports trustworthy decisions

Manufactured to DIN EN ISO 3650 and rated Grade 1, this precision end gauge delivers a narrowly defined tolerance band that underpins objective pass/fail decisions in production and lab environments. The nominal size of 1.21 mm is produced with tight dimensional control, enabling it to serve as a reference for small-feature inspection or as a member of a master gauge set. The combination of standard conformity and measurable specification reduces ambiguity during inspections and offers a clear technical basis for quality documentation.

Built for repeatability and long service life

Constructed from hardened special steel, the gauge resists wear and maintains its form through repeated contact with measured parts. The specified cross-section of 30 x 9 mm (applicable for sizes up to 10 mm) provides a balance between rigidity and ease of handling, keeping deformation and thermal influence minimal during use. Low mass (0.005 kg) contributes to reduced thermal drift and simple positioning on fine parts, supporting reproducible measurements with less operator-induced variability.

Integrates cleanly into quality workflows

This precision gauge is designed for straightforward inclusion in inspection routines and gauge sets; its traceable identifiers support inventory control and documentation. The product is listed with GTIN and customs tariff information to simplify logistics and compliance in procurement processes. As a standardised measuring tool, it complements comparators, microscope-assisted checks and manual gauge benches, providing a compact, reliable reference for small-diameter verification tasks.
