M72x4 Thread Ring Gauge Metric ISO Fine Thread Right Hand, Hardened Gauge Steel, DIN 13 6g, Calibrated Certificate - Metav IndustryLine

Take control of thread quality with a robust inspection tool: the combination of precise DIN‑class tolerance, hardened gauge steel construction, and an included calibration certificate ensures repeatable rejection of out‑of‑tolerance threads and reduces rework. Order the thread ring gauge directly via Metav Werkzeuge or ask our consultants if needed.

Thread Ring Gauge M72 x 4.0 No‑Go (right‑hand) — Metav IndustryLine

The Thread Ring Gauge M72 x 4.0 No‑Go is a right‑hand thread inspection gauge designed for production and incoming‑inspection tasks, checking conformity to ISO/DIN metric fine thread tolerances.

• Right‑hand M72 x 4.0 thread
• No‑Go gauge for reliable reject control
• Hardened gauge steel for long service life
• Supplied with calibration certificate

Consistent tolerance control for production reliability

A dedicated No‑Go ring gauge provides a direct, binary check that a threaded part exceeds allowable limits. By referencing DIN 13 (6g) and the nominal M72 x 4.0 geometry, this gauge gives an immediate go/no‑go decision at the inspection point. The result is faster quality gates, fewer ambiguous measurements and a lower risk of costly rework. The clear mechanical pass/fail principle is ideal where throughput and certainty are priorities in workshop and production environments.

Robust construction that reduces lifecycle costs

Manufactured from hardened gauge steel, the ring offers high wear resistance and dimensional stability under repeated use. The material choice and heat treatment minimise profile wear, which preserves gauge accuracy and extends intervals between re‑calibration. The compact, single‑function design simplifies handling while maintaining the stiffness required for accurate assessment of large diameter metric fine threads in serial production.

Calibration and traceability for audit readiness

Delivered with a calibration certificate, this inspection ring supports traceability and quality documentation. The certificate records the inspection status at delivery, enabling integration into quality systems and audit evidence for suppliers and manufacturers. Combined with the DIN tolerance reference, traceable calibration ensures reproducible decisions across shifts and operators, strengthening process reliability and customer confidence.

FAQ

What does the No‑Go designation mean for inspection?
The No‑Go designation indicates the ring functions as a reject gauge: a thread that enters the ring is out of tolerance. The M72 x 4.0 No‑Go ring gauge (SKU M315.872.9) gives an immediate fail indication for non‑conforming threads.

Is a calibration certificate included with delivery?
Yes, the ring gauge is supplied with a calibration certificate that documents the inspection status at delivery and supports traceability in quality records.

Which standard and tolerance class does the gauge reference?
The gauge is manufactured to check metric fine threads against DIN 13 with tolerance class 6g for the M72 x 4.0 nominal size.

What is the ring made from and how durable is it?
The ring is made from hardened gauge steel, chosen for high wear resistance and dimensional stability under repeated use in production environments.

Can this gauge be used for left‑hand threads?
No, this specific ring is a right‑hand thread gauge and is intended for right‑hand metric ISO fine threads.
