Thread ring gauge M12 x 1.25 mm — Metav IndustryLine, DIN 13, 6g

The thread ring gauge M12 x 1.25 mm is a hardened pass/fail ring for inspection of external metric ISO fine threads in production and quality control.

• Hardened gauge steel construction
• DIN 13 tolerance class 6g
• Right-hand metric fine thread fit
• Compact 0.08 kg for easy handling

Ensure fast, unequivocal go/no-go decisions on the shop floor

A hardened ring gauge provides a decisive, repeatable check for external threads; the M12 x 1.25 mm size and tolerance class 6g are specified for metric ISO fine threads to confirm conformity or identify rejects immediately. The robust construction in hardened gauge steel resists wear and maintains the inspection limit, which reduces measurement uncertainty and helps to avoid costly rework. The light mass of 0.08 kg also makes the gauge simple to handle during serial checks, enabling efficient throughput without sacrificing accuracy.

Built for traceability and compliant inspection routines

The gauge is manufactured to DIN 13 and marked for right-hand threads, so it integrates seamlessly into documented quality processes and inspection plans. The simple pass/fail nature supports quick visual decisions and can be recorded in quality logs as part of a statistical process control regime. The metal construction ensures dimensional stability, which improves repeatability across repetitive checks and supports decision-making in both production and incoming inspection.

Practical durability and what it means for daily use

Made from hardened gauge steel, the ring gauge withstands normal workshop wear and preserves the inspection limit over many cycles, meaning fewer tool replacements and consistent results. The adherence to DIN standards and a defined tolerance class simplifies communication with suppliers and inspectors and avoids ambiguity about acceptance criteria. For applications that demand clear go/no-go verification of metric fine threads, this gauge offers a straightforward and low‑effort solution that focuses on reliable outcomes rather than complex measurement procedures.

FAQ

What is the intended use of this ring gauge?
This ring gauge is designed for go/no-go inspection of external metric ISO fine threads, specifically M12 x 1.25 mm, to confirm conformity with DIN 13 and tolerance class 6g.

How does the tolerance class 6g affect acceptance criteria?
Tolerance class 6g defines the dimensional limits for an external thread; the ring gauge is manufactured to that class so a pass indicates the thread is within the specified acceptance range.

Is the gauge suitable for serial production checks?
Yes, the hardened gauge steel construction and compact weight make it appropriate for frequent pass/fail checks in serial production and incoming inspection.

What maintenance is required to keep the gauge reliable?
Routine cleaning and protection from abrasive contamination will preserve the gauge. Periodic verification against a master or calibration standard is recommended to ensure ongoing conformance.
