M313.350 Setting ring 350 mm — hardened gauge steel, Form C (Metav IndustryLine)

The M313.350 setting ring is a precision ring gauge designed for calibration and verification tasks in inspection, gauge room and workshop applications, providing a stable reference at a nominal diameter of 350 mm.

• Hardened gauge steel, lapped finish
• Conforms to DIN 2250 / DIN 286, JS4
• 350 mm nominal diameter, Form C accuracy

Precision and conformity for calibration tasks

The setting ring is manufactured from hardened gauge steel with a lapped finish, producing a stable, wear‑resistant measuring surface that is suitable as a master for calibration and go/no‑go verification. Conformity to DIN 2250 and DIN 286 with tolerance class JS4 ensures that the ring can be used where documented traceability and repeatable comparison measurements are required. The nominal diameter of 350 mm is achieved and controlled during production to provide a reliable reference for ring gauges, mandrels and mating components, reducing uncertainty in routine inspection tasks.

Built for repeatability and workshop durability

Robust construction and surface finishing minimise surface wear and maintain form over repeated use, so reproducible results are delivered without frequent adjustment. The Form C profile is suitable for many standard calibration procedures and is dimensionally stable thanks to controlled hardening and precision lapping. The mass and section of the ring contribute to thermal and mechanical stability during measurement, which supports consistent readings when used in a controlled inspection environment. This design reduces the need for corrective interventions and simplifies routine quality checks.

Seamless integration into inspection workflows

The ring gauge is intended to be integrated into standard inspection workflows where documented conformity and clear identification are important. Identification data such as GTIN and article number enable straightforward inventory and quality‑management tracking, while compatibility with established calibration procedures supports accreditation paths. Use of this ring as a master reference streamlines comparative measurements and assists in maintaining instrument traceability across the workshop or laboratory, improving process control and audit readiness.
