Setting ring M313.048 — 48 mm, Form C, hardened gauge steel (Metav IndustryLine)

The Setting ring M313.048 is a precision ring gauge made to DIN 2250 in Form C, intended as a robust reference for diameter checks and setting tasks in workshop and inspection environments.

• Setting ring M313.048, Form C
• Diameter 48 mm, weight 0.6 kg
• Hardened and lapped gauge steel
• Tolerance JS 3 to DIN 2250 and DIN 286

Reliable reference for dimensional control

A hardened ring gauge provides a stable master for routine checks and setting operations. The 48 mm diameter and JS 3 tolerance class mean the component serves as a tight reference for production or incoming inspection, helping to reduce measuring uncertainty. By offering a repeatable datum in a compact form, the ring simplifies adjustment of measuring instruments and fixtures and supports consistent quality control across production batches.

Long-term stability through material and finish

Manufactured from hardened and lapped gauge steel, the component resists wear and maintains form accuracy under typical workshop use. The lapped bore reduces surface roughness and ensures precise contact with shafts or pins, while the hardened substrate protects against deformation. Together these features extend service life and limit the need for frequent replacement, making the gauge a cost-effective element in any inspection toolkit.

Standards compliance for traceable inspection

Designed to the requirements of DIN 2250 and DIN 286, the ring gauge meets recognised German standards for gauging geometry and tolerancing. The conformity to these norms facilitates integration into existing quality systems and documentation practices. As a standardised master, the gauge aids traceability in measurement procedures and supports consistent acceptance criteria between suppliers and customers.

Practical handling and workshop use

The Form C design balances accessibility and seating stability, allowing straightforward engagement with shafts and fixtures in a production environment. At 0.6 kg the part is easy to handle without sacrificing rigidity, and the compact size suits toolrooms and bench applications where space and repeatability matter. The ring is appropriate as a setting master for comparative measurement and for verifying external diameters within the stated tolerance class.
