Thread plug gauge M20 x 0.5 mm — Go gauge for metric ISO fine threads, right-hand, DIN 13 (6g)

The Thread plug gauge M20 x 0.5 mm is a hardened go gauge designed for rapid acceptance testing of right-hand metric ISO fine threads in production and quality control environments.

• Hardened gauge steel construction
• DIN 13 tolerance class 6g
• For M20 x 0.5 metric fine threads
• Lightweight 0.14 kg for easy handling

Fast, unambiguous pass/fail inspection that saves time

The primary purpose of this gauge is a clear and repeatable go/no-go decision at the workstation. As a Go gauge, the tool verifies that an internal thread meets the dimensional and tolerance band specified by DIN 13 for tolerance class 6g, using the nominal size M20 x 0.5. Employing a dedicated plug gauge for this task reduces inspection time compared with full metrological measurement, removes operator doubt during series checks and integrates easily into inline quality routines. The result is a measurable improvement in throughput and fewer ambiguous inspection outcomes.

Robust construction for sustained workshop use

Made from hardened gauge steel, the plug gauge is built to withstand repeated engagement without significant wear, ensuring long service life and stable inspection results. The compact mass of 0.14 kg simplifies handling during frequent checks and reduces operator fatigue when used across multiple machines or assembly stations. The hardened finish contributes to corrosion resistance in ordinary workshop conditions and maintains dimensional stability under regular use, which supports consistent quality control without frequent replacement.

Practical fit for production, service and tooling stores

This plug gauge suits applications in machining, assembly and incoming inspection where metric ISO fine threads are present. The right‑hand M20 x 0.5 profile is common in precision assemblies and fine-thread fastenings; having a dedicated go gauge avoids costly rework by catching out-of-tolerance threads at the earliest stage. Supplied as a single-purpose inspection tool, it is straightforward to store in a tool cabinet or bench kit and to integrate into standard operating procedures. As part of the Metav IndustryLine range, it reflects the supplier’s commitment to making precision tools accessible to workshops and industry alike.

FAQ

What is the purpose of this plug gauge?
The plug gauge M20 x 0.5 mm is a dedicated Go gauge for quick acceptance testing of internal threads to DIN 13 tolerance class 6g.

Can this gauge be used for both inspection and setting up machines?
Yes, the M20 plug gauge from Metav IndustryLine serves for rapid in-process inspection and can be used during setup to confirm thread form before production runs.

What material is the gauge made from and why does it matter?
The gauge is manufactured from hardened gauge steel, which ensures wear resistance and dimensional stability during repeated use.

Does the gauge indicate tolerance class or only size?
The plug gauge checks the internal thread against the nominal size M20 x 0.5 and the tolerance band of DIN 13 (6g); it provides a go/no-go decision rather than a dimensional measurement.

How should the gauge be stored to maintain accuracy?
Store the plug gauge dry, protected from impact and corrosive environments; repeated careless handling may shorten service life even though the tool is hardened.
