Thread ring gauge M4 x 0.5 — Go ring for metric ISO fine threads (Metav IndustryLine)

The Thread ring gauge M4 x 0.5 is a right-hand Go gauge designed for quick pass/fail verification of metric ISO fine threads in production and inspection environments.

• Go ring for M4 x 0.5 metric fine thread
• Hardened gauge steel construction
• Conforms to DIN 13 tolerance class 6g
• Lightweight 0.02 kg for easy handling

Fast, reproducible pass/fail checks on the shop floor

A compact Go ring provides immediate confirmation that a threaded component meets the defined tolerance. The Go ring principle is straightforward: a correct thread must enter the gauge without forcing, which speeds up quality control and reduces machine downtime. With the nominal size M4 x 0.5 and the industrial DIN 13 6g tolerance class, this gauge is suitable for routine inspections of fine threads commonly found in small assemblies and precision components. The result is a clear, objective decision at the point of manufacture, supporting faster throughput and fewer uncertain measurements.

Durable design that keeps measurement uncertainty low

Manufactured from hardened gauge steel, the ring resists wear and maintains dimensional stability over many cycles, which translates into a longer service life and consistent verification results. The slim, lightweight construction (approx. 0.02 kg) makes the gauge easy to handle and store while remaining robust enough for daily use. Because the component is a Go-type gauge, it is optimised for repeatability: the hardened material and precise finish minimise changes in fit that could otherwise introduce measurement drift, helping to preserve inspection integrity across long production runs.

Conformity and practical benefits for inspection workflows

Compliance with DIN 13 and the 6g tolerance class ensures the gauge matches established thread standards, enabling straightforward integration into existing quality procedures and documentation. The ring is intended for right-hand metric ISO fine threads and serves as a simple, low-effort control instrument where a full-profile inspection is unnecessary or impractical. Used alongside calibrated reference tools, a Go ring like this one reduces processing time for routine checks and supports traceable, standards-based quality management in workshops and industrial environments.

FAQ

What is the purpose of this ring gauge?
The ring is a Go gauge for fast pass/fail verification of metric ISO fine threads; the Metav IndustryLine M4 x 0.5 ring confirms whether a right-hand M4 x 0.5 thread meets the DIN 13, 6g requirement.

Can this gauge be used for production sampling?
Yes. The hardened construction and DIN 13 conformity make the ring suitable for routine production sampling and quick in-process checks.

What does the 6g specification mean?
The 6g designation denotes the thread tolerance class under DIN 13; it defines the permissible limits for the mating external thread that the Go gauge is intended to accept.

Is the material suitable for long-term use?
Hardened gauge steel provides wear resistance and dimensional stability, supporting a long service life under regular inspection cycles.
