Thread ring gauge M20 × 2 mm (No‑Go) — Metav IndustryLine

A Thread ring gauge M20 × 2 mm (No‑Go) for rapid verification of metric ISO fine threads to DIN 13, designed for on‑line and workshop quality control of right‑hand external threads

• No‑go ring for M20×2 threads
• Hardened gauge steel construction
• Manufactured to DIN 13, tolerance 6g

Rapid, unambiguous thread inspection for production

A no‑go ring provides a binary, immediately interpretable result: if the external thread enters the ring, the part is out of tolerance. This Thread ring gauge M20 × 2 mm (No‑Go) is specified for M20×2 metric ISO fine threads and conforms to DIN 13 with tolerance 6g, making it suitable for routine shop‑floor checks and first‑piece inspections. The simple pass/fail principle reduces measurement time compared with dimensional gauging, enabling a steady flow through inspection points and helping to prevent batches of non‑conforming parts from progressing further down the line. Where traceable evidence of conformity is required, the clear go/no‑go outcome simplifies documentation and decision making.

Durable, low‑maintenance construction for high throughput

Manufactured from hardened gauge steel, the ring resists wear and retains form tolerance over extended production runs. The compact mass of 0.12 kg and the robust finish make the gauge easy to handle while remaining stable during repetitive use. Because the gauge is built for repeated engagement with threaded parts, downtime for replacement is minimised and consistency across inspectors is improved. The mechanical simplicity also reduces the need for frequent recalibration compared with more complex measuring instruments, supporting continuous inspection in busy manufacturing environments.

Integrates with existing quality workflows and supplier control

Used as part of a layered inspection concept — alongside functional tests and sampling measurements — this no‑go ring supports rapid decisions at the machine, assembly bench or goods‑in inspection. The ring’s compliance with DIN 13 / 6g aligns it with standard engineering practice, aiding supplier audits and incoming goods checks. Supplied by Metav IndustryLine, the gauge benefits from Metav’s European quality filter and distribution infrastructure, which helps small and medium manufacturers access precision measuring tools reliably and repeatedly.

FAQ

What is the purpose of a no‑go thread ring gauge?
A no‑go thread ring gauge is a functional check: if an external thread enters the ring, the part is rejected. The gauge provides a fast, unambiguous pass/fail decision during inspections.

Can this gauge be used for both coarse and fine threads?
This specific gauge is for M20 × 2 mm metric ISO fine threads (right‑hand) and is not suitable for coarse thread pitches; separate gauges are required for different thread sizes or pitches.

How does the gauge relate to standards and tolerances?
The ring is manufactured to DIN 13 with tolerance class 6g, ensuring compatibility with standard ISO metric thread production and allowing consistent acceptance criteria in quality control.

How often should the ring be checked for wear?
Frequency depends on usage intensity; for high throughput lines a regular inspection schedule is recommended. Visual checks and functional trials against calibrated masters help determine wear before dimensional drift affects results.

Is this gauge suitable for supplier incoming inspection?
Yes. The no‑go ring’s clear pass/fail output and DIN 13 / 6g conformity make it well suited to incoming goods inspection and fast supplier verification.
