Reliable verification for production control

This inspection ring provides a straightforward method for thread verification during incoming goods inspection and in-process quality checks. Manufactured to DIN 13 and tolerance class 6g, the ring gives a definite pass criterion: components that enter the ring comply with the specified thread form and pitch. The hardened construction minimises wear, preserving dimensional integrity over many cycles and supporting consistent, repeatable results in serial production environments.

Designed for workshop durability and easy handling

Made from hardened gauge steel, the ring combines durability with practical handling characteristics; its mass of 0.7 kg makes it stable in manual inspection without being cumbersome. The robust material choice reduces the need for frequent replacement, lowering total cost of ownership through extended service life. Clear thread designation and a compact form factor simplify storage and selection on the inspection bench, enabling faster throughput in routine testing.

Fits quality systems and simplifies documentation

The ring supports standardised quality procedures by delivering an unambiguous go/no-go criterion for M39×4 threads. Traceable identification via SKU M315.139 and GTIN supports inventory and quality records, while the compliance with DIN 13, 6g integrates easily into conformity assessments and inspection plans. For customers seeking reassurance from a reliable supplier, Metav IndustryLine provides a consistent supply chain and documented product specifications that streamline procurement and audit processes.

FAQ

What thread size does this ring check?
The ring checks M39×4 external ISO metric threads; the designation M39×4 is engraved on the ring for identification.

Which tolerance and standard apply to this gauge?
This go ring is manufactured to DIN 13 and tolerance class 6g, providing a clear pass criterion for the specified thread class.

Is this a go or no‑go gauge?
This product is a go ring; parts that enter the ring are acceptable for the specified M39×4 thread form.

What material is the gauge made from and how durable is it?
The gauge is made from hardened gauge steel, offering high wear resistance and long service life suitable for frequent inspection cycles.

Can the gauge be used for left‑hand threads?
No, the ring is for right‑hand ISO metric threads only; left‑hand threads require a dedicated left‑hand gauge.
