Thread ring gauge M20 x 0.75 (DIN 13, 6g) — Metav IndustryLine

The Thread ring gauge M20 x 0.75 is a hardened inspection ring designed for rapid verification of metric ISO fine external threads in production and quality control.

Consistent pass/fail decisions with standard-compliant tolerances

A gauge produced to DIN 13 with 6g tolerance gives a clear, objective criterion for thread acceptance that integrates seamlessly into shop-floor control routines. By providing a fixed reference for the external thread profile, the ring eliminates subjective judgements during visual or tactile inspection and speeds up quality control throughput. The hardened measuring surface preserves dimensional integrity over repeated use, ensuring that each check reflects the original inspection limit rather than wear-induced deviation. This reliability reduces scrap and rework rates, helping to keep production run times predictable.

Durable construction that lowers maintenance needs

Constructed from hardened gauge steel, the ring is engineered for longevity in industrial environments. The material choice minimises wear on the measuring faces and maintains form stability under normal handling. At a weight of 0.12 kg the component is easy to position and rotate by hand, which streamlines repetitive checks without the fatigue associated with heavier gauges. Reduced maintenance and longer service intervals translate into lower total cost of ownership and fewer interruptions to inspection plans.

Clear application guidance for workshop compatibility

The ring is intended for inspection of external, metric ISO fine threads with a thread pitch of 0.75 mm, right-hand orientation. In practice, this means quick verification of turned or machined components such as shafts, fittings and precision fasteners. For shops that adhere to DIN norms, this gauge provides direct compliance evidence for incoming inspection and in-process checks. For teams less familiar with tolerance classes, 6g denotes the standard tolerance zone for external threads, compatible with most mating internal thread classes used in mechanical assemblies.

Trust and supply security from a dedicated metrology partner

Sourcing from Metav IndustryLine offers the logistical and technical backing expected in industrial procurement: consistent stockkeeping from Emmerich, a wide catalogue of metrology items, and experienced advice for matching gauges to measurement tasks. Choosing a standardised inspection tool supports traceable, repeatable testing routines and contributes to documented quality assurance processes. For complex assemblies where thread conformity is critical, a robust ring gauge forms a simple but effective control point that protects component fit and function.

FAQ

What does this gauge check? The ring checks external metric ISO fine threads; the Thread ring gauge M20 x 0.75 confirms whether a part meets the specified thread form and tolerance band.

Is the gauge suitable for production use on turned parts? Yes, the Metav IndustryLine ring is designed for shop-floor inspections of turned and machined external threads where fast, repeatable acceptance checks are required.

What does the 6g tolerance indicate? The 6g designation refers to the external thread tolerance class per DIN 13 and specifies the acceptable size band for mating with standard internal threads.

Can the gauge be used for both fine and coarse thread series? This specific item is for a fine thread pitch of 0.75 mm; different ring gauges are required for other pitches or coarse thread series.
