Faster assurance of thread conformity for production use

A Go ring gauge performs a rapid functional check: it confirms whether a thread meets the minimum dimensional and form requirements. Built as a Go gauge to the G 7/8 Whitworth profile with 14 tpi, this ring provides a clear go/no‑go decision at the shop floor. Compliance with DIN ISO 228 and tolerance class A means inspectors gain reproducible acceptance criteria, which reduces rework and shortens throughput times. The technical specification translates directly into operational benefit: quicker checks, fewer rejects and consistent assembly fit.

Durable build for long service life and low maintenance

Constructed from hardened gauge steel, the ring is optimised for repeated engagement without rapid wear, preserving the measurement boundary that defines acceptance. Hardening increases wear resistance and supports stable dimensional behaviour under regular use, so calibration intervals can be planned rather than forced by premature degradation. The compact mass (approx. 0.35 kg) and right‑hand orientation make it straightforward to handle in routine inspection cycles, while the Go‑only function keeps operation simple and unambiguous for shop staff.

Practical integration into quality workflows and traceability

The ring is a purpose‑built inspection tool for process control in workshops and final assembly. As a standardised gauge it supports traceable acceptance checks and simplifies documentation of inspections. The compact design and clear specification (pitch 14 tpi, tolerance class A) allow easy inclusion into quality plans and control charts. Supplied under the Metav IndustryLine range, it benefits from Metav’s European logistics and product support, which helps maintain availability for recurring inspection needs and prevents production delays.

FAQ

What does the Go designation mean for this ring gauge?
The Go designation indicates that the ring gauge checks whether a thread meets the minimum acceptable form and size; the Pipe Thread Master Ring Gauge G 7/8 GO Whitworth (M315.327) permits threads that are within specification to pass.

Is this gauge suitable for production line checks?
Yes. The hardened construction and tolerance class A make the gauge suitable for frequent production checks and process control in workshop environments.

Which thread form and pitch does the gauge verify?
The gauge verifies the Whitworth pipe thread form for G 7/8 with a pitch of 14 tpi, ensuring compatibility with corresponding thread specifications.

Does the ring comply with recognised standards?
The ring is manufactured to DIN ISO 228 standards, providing a clear, documented basis for acceptance checks.

How does the material affect longevity and maintenance?
Made from hardened gauge steel, the ring offers enhanced wear resistance, which supports predictable calibration intervals and reduced maintenance effort.
