Setting ring 33 mm (M313.033) — Ring gauge, Form C, hardened and lapped, Metav IndustryLine

The Setting ring 33 mm is a Form C ring gauge intended as a traceable reference for dimensional inspection, instrument setting and routine quality checks in metrology and workshop environments

• 33 mm diameter, Form C
• Hardened and lapped gauge steel
• DIN 2250 / DIN 286 compliant
• Tolerance grade JS 3

Consistent reference for inspection and process control

A compact 33 mm ring gauge supplies a stable, repeatable reference that supports fast in‑process checks and instrument setting. The conformity to DIN 2250 and DIN 286 with tolerance JS 3 ensures that measurements made against this ring are traceable to recognised national standards, reducing ambiguity in pass/fail decisions. Using a standardised reference speeds calibration routines and lowers the rate of rework, thereby improving production throughput and measurement reliability.

Hardened, lapped construction for long service life

Manufactured from hardened gauge steel and finished by lapping, this ring gauge delivers a wear‑resistant measuring surface with a fine contact finish. The hardening process increases resistance to abrasion and deformation, while the lapped surface minimises micro‑asperities that can cause repeatability errors. The result is a durable reference standard that maintains dimensional stability under frequent use, translating into fewer replacements and a lower total cost of ownership.

Practical advantages in the workshop and quality lab

The Form C geometry provides a compact profile that is easy to seat and align during measurement tasks, making the gauge practical for rapid checks and for setting calipers or micrometers. As a purpose‑made ring gauge, it integrates naturally into inspection jigs and test benches and streamlines standard operating procedures. Clear standards compliance and robust material choice combine to deliver reproducible results and dependable documentation for quality control workflows.

FAQ

What is the intended use of this ring gauge?
The setting ring 33 mm (ring gauge, M313.033) is designed as a reference for dimensional inspection, instrument setting and routine quality checks in workshops and inspection labs.

Which standards does the gauge meet?
The ring gauge conforms to DIN 2250 and DIN 286 and is supplied to tolerance grade JS 3 for consistent, standardised inspections.

How does the hardened and lapped finish benefit measurement?
Hardened, lapped surfaces on the setting ring minimise wear and provide a fine contact surface that improves repeatability and long‑term dimensional stability during frequent checks.

Can this gauge be used for setting calipers and micrometers?
Yes. The Form C design and the precise 33 mm diameter make the gauge suitable for setting and verifying measuring instruments as part of routine calibration and setup tasks.
