Thread ring gauge M42 x 4.5 (No‑go) — hardened gauge steel, DIN 13 (6g) — Metav IndustryLine

The Thread ring gauge M42 x 4.5 (No‑go) verifies metric ISO right‑hand threads to DIN 13 and serves as a rejection gauge for quality control in machining and assembly processes.

• No‑go thread ring gauge for M42 x 4.5
• Hardened gauge steel, robust and wear‑resistant
• Manufactured to DIN 13, tolerance 6g

Reproducible thread inspection for production control

A dedicated no‑go ring provides a clear, binary check that indicates whether a threaded part exceeds allowable upper limits. Manufactured to DIN 13 with tolerance 6g, this ring establishes an objective acceptance boundary for metric ISO threads. Used in routine control, the component delivers rapid pass/fail decisions that reduce downstream rework and help maintain consistent assembly fit. The specification is intelligible for quality engineers and operators alike, enabling traceable inspection without complex measurement routines.

Durable material choice that lowers life‑cycle costs

Constructed from hardened gauge steel, the ring is designed to withstand frequent engagement with threaded parts while preserving thread form and tolerance. The hardening process reduces wear and the need for frequent replacement, which directly contributes to lower life‑cycle costs in busy production lines. Robust construction also maintains measurement integrity over time, supporting reproducible results and minimising interruptions for maintenance or replacement.

Practical integration into workshop quality procedures

The no‑go ring is intended to be paired with the corresponding go gauge as part of a go/no‑go inspection routine or used independently where a fast rejection criterion is required. It suits workshop and shop‑floor applications in machining, bolt production and component assembly where metric ISO threads are standard. By anchoring thread checks in a simple physical limit, the device simplifies staff training and accelerates inspection throughput without sacrificing compliance with specified tolerances.

Clear handling and specification benefits for procurement

The compact, single‑purpose design eliminates setup time associated with instrument-based measurements, while the DIN 13 designation and M42 x 4.5 marking ensure unambiguous specification in procurement and quality documentation. Traceable labelling and the established standard make the gauge straightforward to reference in inspection plans, inspection reports and incoming goods checks, supporting efficient supplier acceptance and internal quality audits.

FAQ

What is the intended use of this ring gauge?
The Thread ring gauge M42 x 4.5 (Metav IndustryLine) is designed as a no‑go (rejection) gauge for swift pass/fail inspection of metric ISO right‑hand threads to DIN 13 with tolerance 6g.

Can this gauge replace measurement instruments for routine checks?
For routine production control, the no‑go ring gauge provides faster, repeatable rejection decisions than dimensional instruments; however, detailed metrological analysis still requires calibrated measuring tools.

Is the ring suitable for use on coated or plated threads?
The Metav IndustryLine no‑go ring gauge checks thread form; when coatings or platings are present, consideration of coating thickness in tolerance planning is recommended before relying solely on the ring for acceptance.

How should the gauge be used in a go/no‑go system?
Used alongside the corresponding go gauge, the no‑go ring establishes the upper limit; parts that fit the go gauge and do not engage the no‑go ring meet the specified acceptance window for threaded components.

How is the specification documented for audits?
The DIN 13 reference, tolerance class 6g and the marking M42 x 4.5 should be recorded in inspection plans and supplier documentation to ensure traceability of the acceptance criterion.
