Thread Ring Gauge M68 x 3.0 — No‑Go, Metric ISO Fine Thread (right‑hand)

The Thread Ring Gauge M68 x 3.0 is a hardened no‑go ring for right‑hand metric ISO fine threads, intended for rapid in‑process and incoming‑goods inspection in industrial environments.

• Hardened gauge steel construction
• Conforms to DIN 13, tolerance class 6g
• Supplied with a calibration certificate
• No‑go function for immediate pass/fail control

Rapid pass/fail inspection for reliable production flow

A dedicated no‑go ring such as this M68 x 3.0 variant turns thread assessment into an immediate, objective decision. The instrument is designed to verify that external threads exceed the maximum allowable material limit: if the ring does not pass, the part is rejected. This direct function reduces subjective judgement and accelerates quality gates on the shop floor, ensuring defective items are identified before downstream processing. Conformity with DIN 13 and 6g tolerance class provides a recognisable standard for procurement and documentation in production control.

Durable, hardened construction for long service life

Manufactured from hardened gauge steel, the ring offers dimensional stability and wear resistance that preserve gauge integrity under regular use. The hardened material minimizes profile degradation, so measurement uncertainty remains low over many cycles. For workshop logistics, a compact, robust gauge like this reduces downtime for replacements and supports repeatable checks on batches and prototypes. The right‑hand thread geometry and solid construction make the instrument suitable for routine verification of metric ISO fine threads where reproducible results are required.

Traceable calibration for audit‑ready inspection records

The product is supplied complete with a calibration certificate, enabling traceability in quality systems and simplifying audit preparation. Calibration documentation confirms the ring’s conformity at delivery and supports integration into inspection plans and measurement records. As a Metav IndustryLine item, the gauge benefits from a controlled supply chain: Metav’s European quality filter and stocked distribution mean documentation and provenance are kept transparent and consistent across orders.

FAQ

What is the primary purpose of a no‑go ring gauge?
A no‑go ring gauge provides a quick pass/fail check: the Thread Ring Gauge M68 x 3.0 verifies that external threads do not exceed the maximum material condition specified by the standard.

Is the gauge delivered calibrated?
Yes, the ring is supplied with a calibration certificate confirming its measurement status at delivery.

Which thread standard and tolerance does the gauge match?
The instrument conforms to DIN 13 and is manufactured to tolerance class 6g for metric ISO fine threads.

Can this gauge be used for left‑hand threads?
This specific model is configured for right‑hand threads; left‑hand versions require a different ring geometry.

What material is the gauge made from and why does that matter?
The ring is made from hardened gauge steel, chosen for dimensional stability and wear resistance to maintain repeatable inspection over time.
