Thread ring gauge G 2 (Whitworth), right-hand — Metav IndustryLine

Thread ring gauge G 2 (Whitworth), right-hand designed for inspection of parallel pipe threads in workshop and production environments

• Hardened gauge steel construction
• DIN ISO 228 pipe-thread standard
• Tolerance class A for precise checks
• Right-hand Whitworth variant

Reliable verification for pipe threads on the shop floor

A thread ring gauge is a direct-pass/fail control tool that confirms whether a manufactured thread meets the required form and size. Built from hardened gauge steel, this ring offers resistance to wear and maintains a stable reference over repeated use, reducing the need for frequent replacement. Conformity to DIN ISO 228 ensures compatibility with standard parallel pipe-thread specifications, while tolerance class A provides a clear acceptance criterion for production lot checks. Using a hardened ring for go/no‑go verification speeds up quality control and helps maintain stable process capability.

Practical advantages that keep inspections efficient

The compact, robust design and the right-hand configuration make the gauge simple to fit and remove during routine sampling. With a nominal designation of G 2" and a thread pitch value of 11, the piece is suited to the relevant parallel pipe-thread sizes encountered in plumbing and machine installations. The unit weight of 1.2 kg gives it a reassuring mass for hand operation without being cumbersome. For shop environments that require quick decision-making, a clearly defined acceptance ring reduces interpretation time and improves throughput in incoming or in‑process inspection.

Integration into quality workflows and traceability

The ring is supplied with visible markings and an identifiable SKU for traceability in inspection records; this allows the gauge to be referenced directly in inspection plans and measurement logs. As a mechanical gauge, it delivers a fast, deterministic check that complements dimensional measuring equipment: use it as a first-line control to catch gross deviations before committing parts to further processing. If a ring is marked as non-conforming or flagged during inspection, ensure it is quarantined and requalified before reuse to maintain measurement integrity.

FAQ

What thread size does this gauge check?
The M315.412 thread ring gauge is specified for G 2" parallel pipe threads and marked for use with the corresponding Whitworth variant.

Is the gauge suitable for production QC use?
Yes, the hardened construction and tolerance class A make the gauge appropriate for routine production and incoming inspection tasks.

Which standard does the ring comply with?
Compliance is to DIN ISO 228, providing alignment with established parallel pipe-thread criteria.

What material is the gauge made from?
The M315.412 is manufactured from hardened gauge steel to resist wear and preserve accuracy during repeated checks.

What does the non-conforming designation mean for use?
A non-conforming or scrap designation indicates the ring requires assessment before use; do not deploy a flagged gauge for final acceptance checks.
