Setting Ring 88 mm — Hardened gauge steel, DIN 2250 compliant (Metav IndustryLine)

The Setting Ring 88 mm is a precision ring gauge designed for go/no‑go verification and instrument setting in workshop and inspection environments.

• Hardened, lapped gauge steel
• Conforms to DIN 2250 and DIN 286, JS 3
• Form C geometry for secure seating
• Precise 88 mm diameter, weight 1.7 kg

Consistent accuracy for routine inspection

The Setting Ring 88 mm is manufactured from hardened, lapped gauge steel, delivering a stable contact surface that resists wear and maintains form accuracy over many measurement cycles. Conformance to DIN 2250 and DIN 286 with JS 3 tolerance ensures this ring can be used as a reference for setting instruments and carrying out repeatable go/no‑go checks. The standardised tolerance class provides a verifiable basis for quality control routines and reduces uncertainty in comparative measurements.

Robust geometry that supports reliable handling

A compact, dense design with form C seating and a mass of 1.7 kg contributes to stable positioning during checks and minimises the influence of small operator movements. The material finish—lapped after hardening—reduces friction and protects mating gauges and measuring faces. This combination of material hardness and finishing translates into less frequent rework of the gauge, lower maintenance needs and consistent performance in both workshop and inspection‑room contexts.

Practical integration into workshop workflows

Designed as a purpose‑built ring gauge for setting and verification, the product simplifies the transfer of dimensional reference values to micrometers, calipers and comparators. Its precise 88 mm diameter and robust construction make it suitable for repetitive set‑up tasks where time‑efficient and reliable checks contribute directly to process stability. The ring’s standards compliance supports traceability within quality systems and eases documentation when integrating reference artefacts into inspection routines.
