Setting ring 47 mm — hardened gauge steel, DIN 2250 (Metav IndustryLine)

The Setting ring 47 mm is a compact, hardened reference ring for precise gauge and inspection work in workshops and quality labs

• Hardened, lapped gauge steel finish
• DIN 2250 / DIN 286 compliant, JS 3 tolerance
• 47 mm nominal diameter for ring-gauge use
• Solid construction, approx. 0.72 kg mass

Absolute reference for quick gauge checks and tool set-up

A compact ring gauge crafted from hardened gauge steel serves as a robust master reference for everyday inspection tasks and machine set-up. With a 47 mm nominal diameter and a lapped finish, this component offers stable contact geometry that reduces measurement scatter when compared with untreated surfaces. The use of standardised tolerances ensures repeatable comparison checks against plug gauges or bore standards, so process control routines become faster and more transparent. For production environments where small but critical diameters determine downstream quality, this ring provides a verifiable reference that supports consistent setup and reduced rework.

Material choice and standard conformity for traceable results

Constructed from hardened and lapped gauge steel, the ring complies with DIN 2250 and DIN 286 and is manufactured to JS 3 tolerance class. These specifications mean the component is intended to function as a calibrated reference rather than a loose inspection fitment: the combination of hardness and surface finishing resists wear and preserves the effective diameter over many cycles. The standards alignment simplifies documentation in quality systems and supports traceability of inspection results back to a recognised tolerance chain, which is essential for audit-ready measurement regimes.

Form C geometry and handling advantages

The Form C design provides a balanced contact profile for reliable seating in both hand inspection and fixture-mounted checks. At approximately 0.72 kg, the ring is heavy enough to remain stable during measurement yet compact for convenient handling and storage. The lapped internal surface reduces tipping and localised wear when used with contact probes or comparator anvils. For workshops that value ergonomic, repeatable procedures, the ring’s geometry shortens set-up time and reduces the influence of operator technique on short-range dimensional controls.

Suitable applications and practical guidance

This setting ring is intended for use as a master reference in calibration benches, incoming inspection, and machine tool set-up for small-diameter components. Typical applications include verifying broach bores, checking plug and ring gauge wear, and providing a quick reference during first-article inspection. For integration into a controlled process, record the ring’s identification (SKU M313.047) in the quality log and follow regular visual inspection and cleaning intervals to maintain accuracy. If the optimal match for a specific measuring routine is unclear, Metav’s specialists can advise on compatible gauges and documentation practices to ensure measurement reliability.

FAQ

What tolerance class does the setting ring meet?
The setting ring is manufactured to JS 3 tolerance and complies with DIN 2250 and DIN 286, providing a defined clearance class suitable for calibration and repeatable inspection routines.

What material and surface quality are specified?
Made from hardened, lapped gauge steel, the ring features a precision lapped finish that minimises wear and ensures stable contact geometry for comparative measurements.

Is the 47 mm ring suitable as a master reference in production?
Yes. The 47 mm nominal diameter and hardened construction make the component suitable as a master reference for small-diameter checks, quick set-up and routine comparator work.

How should the ring be maintained to preserve accuracy?
Keep the ring clean, dry and free from nicks; handle with care, avoid impacts, and store in a protective compartment when not in use. Regular visual checks after use will help preserve the lapped surface and dimensional integrity.

Can the ring be used with probe-based comparators or manual gauge blocks?
The ring’s lapped internal surface and Form C geometry are compatible with both tactile probe contacts and manual comparator setups; ensure contact fixtures are clean and matched to the ring’s diameter class.
