M20x0.5 Thread Gauge Ring ISO Metric Fine Right-Hand DIN 13, Hardened Gauge Steel - Metav IndustryLine

Taking advantage of a hardened gauge steel body, precise DIN 13 / 6g tolerance and an M20×0.5 fine‑thread form, this ring gauge ensures fast, repeatable go/no‑go checks on right‑hand metric threads; order the ring gauge directly via Metav Werkzeuge or consult the team for application advice.

Thread ring gauge M20 × 0.5 mm – No‑go (right‑hand), hardened gauge steel (Metav IndustryLine)

The Thread ring gauge M20 × 0.5 mm (No‑go) is a hardened ring gauge for quick verification of metric ISO fine threads to DIN 13 with a 6g tolerance, designed for right‑hand threads in production and inspection environments

• Hardened gauge steel construction
• For metric ISO fine thread M20×0.5
• Conforms to DIN 13 tolerance 6g

Fast, unambiguous thread inspection for production lines

A No‑go ring gauge provides an immediate pass/fail decision without lengthy set‑ups or complex measuring programmes. The defined M20×0.5 thread form and the DIN 13 tolerance class 6g reduce interpretation variance and accelerate throughput when checking batches or incoming components. By replacing repetitive dimensional checks with a simple insertion test, inspection cycles become shorter and traceable process gates are established, supporting higher production efficiency and consistent quality control.

Robust material and wear resistance for long service life

Made from hardened gauge steel, the ring maintains thread form under frequent use and resists wear that can otherwise bias inspection results. The compact design and modest mass support easy handling at inspection benches and in-line stations; the durable finish helps to preserve the calibrated condition of the threaded gauge face. This construction lowers maintenance needs and prolongs service intervals, providing reliable repeatability over many inspection repetitions.

Standards compliance to support quality documentation

Manufactured to DIN 13 with a tolerance of 6g, this ring gauge aligns inspection procedures with industry norms for metric ISO fine threads. Using a dedicated No‑go gauge simplifies conformity checks during first article inspection and routine sampling, enabling straightforward documentation of non‑conforming parts. The clear standard reference assists in audit situations and in maintaining consistent acceptance criteria across suppliers and production sites.

Practical handling and integration into workshop routines

The ring gauge is designed for straightforward use on the shop floor: the right‑hand M20×0.5 form fits the relevant mating threads directly for instant verification. Light weight and a compact envelope make the tool easy to store in tool cabinets or inspection kits, while the rigid material supports repeatable tactile feedback during testing. As a purpose‑built verification tool, it minimises operator interpretation and integrates neatly into go/no‑go inspection plans or visual work instructions.

FAQ

What is the ring gauge used for?
The ring gauge is a No‑go verification tool for M20×0.5 metric ISO fine threads; the M20×0.5 No‑go ring gauge (Metav IndustryLine, SKU M315.220.2) confirms whether a threaded part exceeds the permitted maximum material condition.

Does the gauge comply with recognised standards?
Yes, the tool is manufactured to DIN 13 and specified for tolerance class 6g to ensure compatibility with standard thread acceptance criteria.

What material is the gauge made from and why does that matter?
The gauge is made from hardened gauge steel, chosen for wear resistance and dimensional stability so that the M20×0.5 profile remains accurate over long inspection cycles.

Is this a go or a no‑go gauge?
This product is a No‑go (reject) ring gauge intended specifically for detecting oversize or out‑of‑tolerance external threads on right‑hand metric ISO fine threads.
