Take advantage of the combination of hardened, lapped gauge steel, conformity to DIN 2250 / DIN 286 (JS4) and a stable 250 mm reference diameter for reproducible inspection workflows; order the setting ring directly via Metav Werkzeuge or ask our consultants for application advice.

Setting ring 250 mm — Gauge ring, hardened and lapped (Metav IndustryLine)

The Setting ring 250 mm serves as a traceable reference diameter for calibration, inspection and setting tasks in metrology and quality control applications.

• Hardened and lapped gauge steel
• JS4 tolerance per DIN 2250 and DIN 286
• 250 mm reference diameter for repeatable checks
• Form C construction, robust mass for stability

Reliable reference for dimensional control

The gauge ring provides a stable, reproducible diameter that supports precise setting and verification of measuring instruments and fixtures. Manufactured from hardened and lapped gauge steel, the component resists wear and maintains its form under repeated contact, which reduces rework and measurement drift. Compliance with DIN 2250 and DIN 286 and the designation JS4 supply an industry-recognised tolerance class, so the ring functions as a dependable master for comparative measurements and routine inspection tasks.

How the construction improves measurement certainty

Form C construction and a substantial mass of 15.4 kg give the ring inherent stability during handling and use; that mass dampens vibration and reduces the influence of small contact forces. The 250 mm diameter is suitable as a mid‑range reference for gauges, mandrels and setting operations in toolrooms and inspection benches. Lapping the working surface ensures a fine finish that improves contact definition and minimises microslip between the ring and the part or gauge, translating into more consistent repeatability for pass/fail assessments.

Integration into workshop and inspection processes

As a standardised reference device, the ring is used for setting up bore gauges, calibrating measuring heads and verifying master profiles before production runs. The combination of material choice and standard conformity provides a practical balance between robustness and metrological reliability, allowing the ring to be integrated into daily quality routines without frequent reconditioning. Backed by Metav’s distribution and quality assurance, the component supports streamlined procurement and traceable inventory for calibration laboratories and production quality control.
