End Gauge 21.5 mm (DIN EN ISO 3650) — Grade 1, Hardened Special Steel

The End Gauge 21.5 mm serves as a calibrated reference standard for inspection, setting and verification tasks in metrology benches and production quality control.

• DIN EN ISO 3650 Grade 1 accuracy
• Hardened special steel construction
• Nominal size 21.5 mm reference standard

Precision that defines tolerances

The gauge is produced to DIN EN ISO 3650, Grade 1, delivering a reliable reference for acceptance testing and routine inspection tasks. With a nominal size of 21.5 mm, the component provides a tight reference point for plug, bore and limit-gauge comparisons, making it suitable where dimensional certainty is required. The standardised specification ensures compatibility with international inspection routines and supports traceable documentation when incorporated into in-house calibration procedures. This focus on measurable conformity reduces uncertainty in process control and improves decision-making in production.

Built for repeatability and robust handling

Manufactured from hardened special steel, the item resists wear and maintains its geometry across repeated use, supporting stable comparative checks over time. The compact mass and defined cross-section facilitate secure gripping and minimise thermal and tactile distortion during handling. These mechanical properties contribute to consistent measurement cycles and lower risk of accidental deformation, which is essential for a reference piece intended for frequent use in workshop and laboratory environments. Designed as a practical shop-floor standard, the gauge combines durability with simple usability to keep inspection routines efficient.

Integration into quality workflows and documentation

As a Grade 1 reference, the gauge fits seamlessly into existing quality assurance systems for receiving inspection, first-article verification and routine calibration traces. The solid construction and normative conformity allow it to serve as a transfer standard for cross-checking instruments and fixtures. When incorporated into documented inspection plans, the component supports repeatable acceptance criteria and enhances comparability between shifts or sites. In combination with Metav’s advisory services, this reference standard becomes part of a pragmatic supply chain approach that promotes accessible, professional metrology across workshops and small-scale production.
