Setting ring 24 mm — hardened gauge steel, DIN 2250 compliant (Metav IndustryLine)

The Setting ring 24 mm is a DIN‑standard ring gauge manufactured from hardened, lapped gauge steel for precise setting and verification of external measuring instruments and small‑bore components in workshop and inspection environments.

• Hardened, lapped gauge steel
• DIN 2250 / DIN 286, JS 3 tolerance
• 24 mm nominal diameter
• Form C design for easy handling

Built for lasting accuracy

Manufactured from hardened, lapped gauge steel, this ring gauge meets DIN 2250 and DIN 286 requirements with a JS 3 tolerance band, providing a stable reference for frequent use. The material choice and finishing process reduce surface degradation and preserve the measured diameter under repeated contact, which translates into fewer replacements and lower downtime. As a traceable DIN gauge, it supports consistent quality control across batches and shifts.

Compact size that speeds setups

The 24 mm nominal diameter and Form C profile make this gauge particularly suitable for setting external micrometers, comparators and checking small shafts or turned parts. Its compact footprint allows rapid mounting on inspection benches and easy handling during routine quality checks, so measuring instruments can be adjusted quickly and reliably. Reduced handling time directly increases throughput in small‑component production.

Operational benefits and reproducible results

Using a standardised ring gauge improves repeatability of go/no‑go decisions and shortens measurement flows by providing a fixed reference point. Compliance with recognised standards also enhances traceability of measurement procedures and simplifies documentation for internal audits. The robust gauge design minimises wear, maintaining measurement integrity over long service intervals and supporting predictable inspection cycles.

Practical applications and workshop integration

This gauge integrates well with standard inspection toolsets, from bench comparators to hand micrometers, and is ideal for toolrooms, small machine shops and assembly stations where small diameters are common. The ring serves as a quick master for instrument setup and periodic verification, helping to maintain process capability without elaborate fixtures. Compatibility with industry standards ensures interchangeability and straightforward replacement when required.
